Tui Mine
The Tui mine is an abandoned mine on the western slopes of Mount Te Aroha in the Kaimai Range of New Zealand. It was considered to be the most contaminated site in the country, following the cleanup of the former Fruitgrowers Chemical Company site at Māpua, Nelson. History In the 1960s, the Tui mine extracted copper, lead and zinc sulphides. The mine was abandoned in 1973, after the mining company Norpac Mining went bankrupt. Waste, rock ore dumps and mine tailings were left behind. The tailings have significant amounts of zinc and cadmium. The mine tailings are stored behind a dam in a large pool-like area which has an oxidised, solid surface layer. The dam contains over 100,000 cubic metres of very acidic, sulphide-rich tailings. In 1997, there had been no natural plant recolonisation on the tailings for more than 20 years. Environmental issues The tailings dam was considered to be unstable and is leaching various minerals, including heavy metals, into neighbouring water ...

Abandoned Mine
An abandoned mine is a mine or quarry which is no longer producing or operational and, there is no responsible party to finance the cost to address the remediation and/or restoration of the mine feature/site. Terms and definitions vary though the common theme is that the cost to address the hazards is typically borne by the public/taxpayer/government. An abandoned mine may be a hazard to health, safety or, environment. Hazards The term incorporates all types of old mines, including underground shaft mines and drift mines, and surface mines, including quarries and placer mining. Abandoned mines are found throughout the world. They contain many hazards to the unwary who venture around them, including: * Subsidence (collapsing ground) * Blasting caps and other undetonated explosives * Blackdamp accumulating in old mines, which can cause suffocation * Hidden mine shafts, often hidden beneath bushes and grasses and other vegetation that has grown up around the mine entrance * ...

Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

Environmental Issues In New Zealand
The environment of New Zealand is characterised by an endemic flora and fauna which has evolved in near isolation from the rest of the world. The main islands of New Zealand span two biomes, Temperate climate, temperate and Subtropical climate, subtropical, complicated by large mountainous areas above the tree line.Walter, H. & Breckle, S-W. (2002). ''Walter's Vegetation of the Earth: The Ecological Systems of the Geo-Biosphere''. New York: Springer-Verlag, p. 86 There are also New Zealand Subantarctic Islands, numerous smaller islands which extend into the subantarctic. The prevailing weather systems bring significantly more rain to the west of the country. New Zealand's territorial waters cover a much larger area than its landmass and extend over the continental shelf and abyssal plateau in the South Pacific Ocean, Tasman Sea and Southern ocean. Historically having an isolated and endemic ecosystem far into modernity, the arrival of Polynesians about 1300 AD and then later Eu ...

Mining In New Zealand
Mining in New Zealand began when the Māori quarried rock such as argillite in times prior to European colonisation. Mining by Europeans began in the latter half of the 19th century. New Zealand has abundant resources of coal, silver, iron ore, limestone and gold. It ranked 22 in the world in terms of iron ore production and 29th in gold production. The total value of mineral production in New Zealand was $1.5 billion in 2006 (excluding oil and gas). The most important metallic minerals produced are gold (10.62 tonnes), silver (27.2 tonnes) and titanomagnetite ironsand (2.15 million tonnes). A 2008 report estimated that the unexploited resources of just seven core minerals (including gold, copper, iron and molybdenum) totalled around $140 billion in worth. The mining sector makes a significant contribution to the New Zealand economy. In 2004 the value of production from mining (excluding oil and gas) was $1,142 million, or just under 1% of gross domestic product. In 2017 mining co ...

New Zealand Department Of Conservation
The Department of Conservation (DOC; Māori: ''Te Papa Atawhai'') is the public service department of New Zealand charged with the conservation of New Zealand's natural and historical heritage. An advisory body, the New Zealand Conservation Authority (NZCA) is provided to advise DOC and its ministers. In addition there are 15 conservation boards for different areas around the country that provide for interaction between DOC and the public. Function Overview The department was formed on 1 April 1987, as one of several reforms of the public service, when the ''Conservation Act 1987'' was passed to integrate some functions of the Department of Lands and Survey, the Forest Service and the Wildlife Service. This act also set out the majority of the department's responsibilities and roles. As a consequence of Conservation Act all Crown land in New Zealand designated for conservation and protection became managed by the Department of Conservation. This is about 30% of New Z ...

Waikato Times
The ''Waikato Times'' is a daily newspaper published in Hamilton, New Zealand and owned by media business Stuff Ltd. It has a circulation to the greater Waikato region and became a tabloid paper in 2018. The newspaper has won the title of New Zealand Newspaper of the Year (in the category of up to 30,000 circulation) for two consecutive years: 2018 and 2019. History The ''Waikato Times'' started out as the tri-weekly ''Waikato Times and Thames Valley Gazette'', first published by George Jones on 2 May 1872 in Ngāruawāhia but moved to Hamilton in 1875. It was then managed by Messrs Langbridge, Silver, E. M. Edgecumbe, George Edgecumbe and J. S. Bond, who ran a book and stationery shop and changed the Times from tri-weekly to a penny daily in 1896, using Press Association news. For 20 years it competed with the ''Waikato Argus'', until the papers merged in 1915. The paper changed from afternoon to morning production from 5 September 2011, though had changed its Saturday i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cadmium
Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11. Cadmium and its congeners in group 12 are often not considered transition metals, in that they do not have partly filled ''d'' or ''f'' electron shells in the elemental or common oxidation states. The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered in 1817 simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Te Aroha
Te Aroha ( mi, Te Aroha-a-uta) is a rural town in the Waikato region of New Zealand with a population of 3,906 people in the 2013 census, an increase of 138 people since 2006. It is northeast of Hamilton and south of Thames. It sits at the foot of Mount Te Aroha, the highest point in the Kaimai Range. History The name Te Aroha derives from the Māori name of Mount Te Aroha. In one version, Rāhiri, the eponymous ancestor of Ngāti Rāhiri Tumutumu, climbed the mountain and saw his homeland in the distance and felt a sense of love () for it. The town is properly named ; meaning 'inland', so the town is named "love flowing inland". In some Tainui traditions, Rakataura, a tohunga of the ''Tainui'' waka, was one of the first people to leave the waka, settling at Rarotonga / Mount Smart. After a period of time, Rakataura decided to leave Tāmaki Makaurau and travel south, however during the journey his wife Kahukeke died. Eventually Rakataura settled at Te Aroha, naming the ...

Tailings
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
