Lead processing

The Parkes zinc-desilvering process is the most widely used pyrometallurgical method of refining lead bullion. As in smelting, the lead is first melted and again allowed to cool below the freezing point of copper, which crystallizes and, along with any remaining nickel, cobalt, and zinc, is removed by skimming. The lead mix then passes to a reverberatory "softening" furnace, where the temperature is Get price

US4466828A

The present invention concerns a process for smelting nickel which comprises treating nickel-containing material with a reducing gas to reduce the nickel component contained in the nickel-containing material and thereby produce metallic nickel; soaking the thus-obtained material in an ammoniacal aqueous ammonium salt solution and treating it with oxygen or an oxygen-containing gas Get price

Zinc smelting

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific Get price

GOLD AND SILVER

Heap leaching, shown in Exhibit 3, is the least expensive process and therefore, low value ores are most often treated by heap leaching. In 1993, heap leaching account ed for 39 percent of gold production.9 In many cases, heaps are constructed on lined pads with ore sent directly from the mine with little or no preparation. However, at about Get price

Processing, smelting and refining gold

The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. Get price

Copper Purification Process

Purification of Impure Copper can be Achieved by Electrolytic Refining What is impure copper: The smelting process takes copper ore and processes it into metal. This metal (sometimes called "blister copper" contains other metals (impurities) which often include valuable metals as gold, silver, arsenic, platinum and others. Get price

Difference between Melting and Smelting

On the other hand, smelting is a process of extracting metals from ores in its purest from. It is a process that involves chemicals and heat to melt the ore and convert it into pure metals. Smelting is done for basic metals like iron, copper, silver and gold. Chemicals such as reducing agents are used to wash out other elements from ores into Get price

Impacts of Smelting

Smelting is known to be a major cause of pollution in the environment. When smelting occurs, along with the metal produced, a solid waste product, called stag, is also produced [1]. This slag is emitted into the air and can be a cause of the pollution although not a major one. The majority of the pollution is caused by air emissions [1]. Get price

Refining Gold

The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.Refining companies receive dor bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample is then taken to a lab for tests, or Get price

Refining (metallurgy)

In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used are of many types, including pyrometallurgical and Get price
