Kier (industrial)
A kier or keeve (or similar spellings) is a large circular boiler or vat used in bleaching or scouring cotton fabric. They were also used for processing paper pulp. In use they were continuously rotated by an engine, steam being supplied through a rotating joint in the axle. They were usually spherical, sometimes cylindrical, and some were recycled from old boiler shells. Kier boiling Kier, the cylindrical-shaped vessel, straight, with egg-shaped ends made of boiler may have the capacity to process one to three tons of material at a time. Kier boiling and ''Boiling off'' is the scouring process that involves boiling the materials with the caustic solution in the Kier, which is an enclosed vessel, so that the fabric can boil under pressure. Open kiers were also used with temperatures below 100°C (at atmospheric pressure).

Ore Dressing
In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores. History Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called "spalling". Before long, mechanical means were found to achieve this. For instance, stamp mills were used in Samarkand as early as 973. They were also in use in medieval Persia. By the 11th century, stamp mills were in widespread use throughout the medieval Islamic world, from Islamic Spain and North Africa in the west to Central Asia in the east. A later example was the Cornish stamps, consisting of a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling onto the ore under gravity. The simplest method of separating ore from gangue consists of picking out the individual crystals of each. This is a very tedious process, particularly when the indi ...

Cider
Cider ( ) is an alcoholic beverage made from the fermented juice of apples. Cider is widely available in the United Kingdom (particularly in the West Country) and the Republic of Ireland. The UK has the world's highest per capita consumption, as well as the largest cider-producing companies. Ciders from the South West of England are generally higher in alcoholic content. Cider is also popular in many Commonwealth countries, such as India, Canada, Australia, and New Zealand. As well as the UK and its former colonies, cider is popular in Portugal (mainly in Minho and Madeira), France (particularly Normandy and Brittany), Friuli, and northern Spain (specifically Asturias). Central Europe also has its own types of cider with Rhineland-Palatinate and Hesse producing a particularly tart version known as Apfelwein. In the U.S., varieties of fermented cider are often called ''hard cider'' to distinguish alcoholic cider from non-alcoholic apple cider or "sweet cider", also made from ...
