Anode Slime
Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the economical and straightforward purification of non-ferrous metals. The resulting metals are said to be ''electrowon''. In electrowinning, an electrical current is passed from an inert anode (oxidation, made out of lead (Pb)) through a ''leach'' solution containing the dissolved metal ions so that the metal is recovered as it is deposited in an electroplating process onto the cathode (reduction, stainless steel, aluminium (Al), titanium (Ti)). In electrorefining, the anode consists of the impure metal (e.g., copper) to be refined. The impure metallic anode is oxidized and the metal dissolves into solution. The metal ions migrate through the acidi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sodium
Sodium is a chemical element with the symbol Na (from Latin ''natrium'') and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature, and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide (lye) is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals inc ...

Chemical Processes
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt ( sodium chloride) and refined sugar ( sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids ...

Electrochemical Engineering
Electrochemical engineering is the branch of chemical engineering dealing with the technological applications of electrochemical phenomena, such as electrosynthesis of chemicals, electrowinning and refining of metals, flow batteries and fuel cells, surface modification by electrodeposition, electrochemical separations and corrosion. This discipline is an overlap between electrochemistry and chemical engineering. According with the IUPAC, the term ''electrochemical engineering'' is reserved for electricity intensive processes for industrial or energy storage applications, and should not be confused with ''applied electrochemistry'', which comprises small batteries, amperometric sensors, microfluidic devices, microelectrodes, solid-state devices, voltammetry at disc electrodes, etc. More than 6% of the electricity is consumed by large-scale electrochemical operations in the US. Scope Electrochemical engineering combines the study of heterogeneous charge transfer at electrode/elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reticulated Cathode
Reticulation is a net-like pattern, arrangement, or structure. Reticulation or Reticulated may refer to: * Reticulation (single-access key), a structure of an identification tree, where there are several possible routes to a correct identification * A coloration pattern of some animals (e.g. the reticulated giraffe) * An arrangement of veins in a leaf, with the veins interconnected like a network * The endoplasmic reticulum within a cell, often resembling a net * A phylogenetic network, the result when hybrid speciation, introgression and parapyletic speciation is applied to a phylogenetic tree * Reticulated water (Australia, South Africa), water from a piped network rather than from a bore or well, see: wiktionary:reticulated water *Reticulation (metalwork) In metalwork, reticulation refers to a decorative surface finishing technique involving the application of localised heat to the surface of a metal object. Reticulation is typically performed on alloys of silver and copp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balbach And Sons Refining And Smelting Company
Balbach Smelting & Refining Company (also known as Balbach and Sons Refining and Smelting Company) was a smelting plant in Newark, New Jersey operating in the late 19th and early 20th centuries. It was the first commercial electrolytic refinery in the United States, and until its closure in the 1920s, it was the second largest metal processing enterprise in the United States. History The company president was Edward Balbach Jr., a metallurgist born in 1839 in Karlsruhe, Baden, Germany. He came to the United States in 1848 with his father Edward Balbach Sr. (1804–1890), who started the Balbach family fortune by collecting gold and silver dust from Newark jewelry shop floors, turning it into bullion. In 1865, Edward Balbach Jr. patented the "Balbach Process" which separated gold and silver from lead, which in 1872 evolved into something closely resembling the Parkes process, which had been developed earlier (1850) in England. In 1881, the Balbachs began to manufacture copper, jus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pembrey
Pembrey ( Welsh: ''Pen-bre'') is a village in Carmarthenshire, Wales, situated between Burry Port and Kidwelly, overlooking Carmarthen Bay, with a population of about 2,154 in 2011. The electoral ward having a population of 4,301. It is in the community of Pembrey and Burry Port Town. History The name Pembrey is an Anglicisation of the Welsh, ''Pen-bre''. "Pen" is a Welsh word meaning head or top, and "bre" is an old Celtic word for a promontory. The coastline began its retreat from the foot of Pembrey Mountain some 6,000 years ago, revealing land which shows human occupation since the Iron Age, with hill forts dating from around 400 BC. The population of the region was known to the Romans as Demetae. Roman pottery remains have been unearthed in the oldest parts of the village. Later, the village was part of the Welsh principality of Deheubarth. Evidence of an early Norman motte-and-bailey castle has been suggested close to the village square and buildings remain in ...
