Chat Online· Process challenges. One of the first process related challenges with nickel laterites is the low and variable grade. Most attempts to upgrade feed material into a hydrometallurgical plant have
Chat OnlineOne of the most used processes to treat nickel and cobalt "speiss" is that used by the company Sherritt Gordon Mines Ltd from Fort Saskatchewan Alberta Canada. Sherritt Gordon Process The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral re-concentrating it through crushing and flotation/gravity and obtaining a "speiss" rich in cobalt and nickel.

Chat OnlineIn hydrometallurgical processes nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte further processing is done via the Sherritt-Gordon process. First copper is removed by adding hydrogen sulfide leaving a concentrate of only cobalt and nickel. Then solvent extraction is used to separate the cobalt and nickel with the final
Chat Online· Historically a number of processes have been used commercially for cobalt separation from nickel in liquor but currently the favoured process is the selective solvent extraction of cobalt away from nickel using phosphinic acid derivatives e.g. Cyanex 272. Although this extractant
Chat Online· Environmental Impacts of Nickel Mining and Processing. Posted by Adrienne Krieger on April 29 2018. Nickel is a widely used alloy in the jewelry industry as an additive to make a variation of white gold. We sometimes refer to this type of white gold as "nickel-white" however it is the standard in the US and when talking about white gold.
Chat Online· The mining of laterites is basically an earth-moving operation with large shovels draglines or front-end loaders extracting the nickel-rich strata and discarding large boulders and waste material. The ore is loaded into trucks at the face as would be the case in an open pit and hauled to the smelter.
