Zinc smelting - Wikipedia

The electrolysis process, also known as the hydrometallurgical process, Roast-Leach-Electrowin (RLE) process, or electrolytic process, is more widely used than the pyrometallurgical processes. The electrolysis process consists of 4 steps: leaching, purification, electrolysis, and melting and casting. The basic leaching chemical formula that drives this process is: This is achieved in practice through a process called double leaching. The calcine is first leached in a neutral or slightly acidic solution (of sulfuric acid) in order to leach the zinc out of the zinc oxide. The remaining

Copper extraction - Wikipedia

Copper concentrate is traded either via spot contracts or under long term contracts as an intermediate product in its own right. Often the smelter sells the copper metal itself on behalf of the miner. The miner is paid the price at the time that the smelter-refiner makes the sale, not at the price on the date of delivery of the concentrate.

Nickel Smelting and Refining - IFC

Flash smelting is the most common process in modern technology, but electric smelting is used for more complex raw materials when increased flexibility is needed. Both processes use dried concentrates. Electric smelting requires a roast-ing step before smelting to reduce sulfur content and volatiles. Older nickel-smelting
