Traditional nickel laterite processing techniques use large quantities of sulphuric acid at high temperatures and pressures, resulting in expensive waste treatment and disposal of the chemicals used in the extraction process. Nickel laterites are becoming a priority for mining companies as traditional nickel sulphide reserves are depleted.

The making of Nickel is a process which involves a number of steps. Mining. Nickel mined from lateritic ore is mined from various depths beneath the surface using large earth-moving equipment. The other nickel containing type of ore, sulfidic ore, is usually found in combination with copper ore and is mined underground.

1.1 Copper-nickel sulfide ore crushing stage Adopt a two-stage closed-circuit crushing process. ① Use a jaw crusher for primary crushing. ② Use a cone crusher for fine crushing. ③ Use a vibrating feeder to screen out the products whose size meets the grinding requirements, while the oversized ones are returned to the cone crusher.

Nickel Refining Various processes are used to refine nickel matte. Fluid bed roasting and chlorine-hydrogen reduc-tion produce high-grade nickel oxides (more than 95% nickel). Vapor processes such as the carbo-nyl process can be used to produce high-purity nickel pellets. In this process, copper and precious metals remain as a pyrophoric ...

The mining and processing of nickel-rich ores can generate high loadings of dust in the air that contains high concentrations of potentially toxic metals including nickel itself copperGet price. Extraction of Nickel .

The process yields matte, a refined ore with 44% nickel content. Batches of matte are then tapped from the sides of the furnace into ladles and transferred to converters. More flux is added, and air is blown through to oxidize the iron and sulfur. This results in a high-grade matte containing 72% nickel, 19% sulfur, and 5%–6% copper.

In addition, the video explains the techniques we use to find nickel and copper. About us: Eagle Mine is a nickel-copper mine located in Michigan's Upper Peninsula. The underground mine is...

The Nickel Mining Process It's not unexpected that the mining processes for nickel differ because nickel is found in two quite different forms of ore. Although some deposits were mined using open pits in the early phases, sulfide deposits are mainly mined using underground techniques similar to copper.

Mining, mineral processing and metal extraction are undergoing a profound transformation as a result of two revolutions in the making—one, advances in digital technologies and the other, availability of electricity from renewable energy sources at affordable prices. The demand for new metals and materials has also arisen concurrently.
