Apr 12, 2016 The Problem with Chromite Processing. Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the ore is minus 16 mesh, it is obvious

The key drivers for the production of chrome are the ferrochrome and stainless steel industries. Some 85% of all chrome produced is converted into ferrochrome by a smelting process. Ferrochrome is a raw material used in the manufacturing of stainless steel. Chrome is also used in the chemical and foundry industry, this is houses small in comparison to the stainless steel industry.
In the electrolytic process, milled high-carbon ferrochromium is leached by a mixture of reduced anolyte (electrolytic solution recycled from the anode side of the smelting cell), a chrome alum mother liquor based on a solution of ammonium sulfate recycled from a later stage in the process, and sulfuric acid. The resultant slurry is cooled, and silica and other undissolved solids are filtered from the solution.

the earth’s mantle, it is referred to as chrome ore. Chrome ore is crushed, screened, jigged into chrome concentrate and then smelted into ferrochrome. Ferrochrome, with nickel, is then processed into stainless steel. The processing of chromite is depicted in Figure 1.
Jul 20, 2017 Approximately 150 pounds of ore were stage crushed with rolls to minus 35 mesh, then blended and sampled for screen analysis. The results of the screen analysis, given in table 2, show that 48.3 pct passed 100 mesh, the point of chromite liberation. The minus 35-mesh stage crushed ore was slurried and tabled to produce a rougher concentrate.
Aug 19, 2008 The process at Millsell involves six stages, the first of which is the obviously the mining that produces the tailings. The mines, in upgrading the chromite content of their ore, produce a tailings stream that contains the majority of the PGMs of the ROM chrome ores. It is these chrome ores with elevated levels of PGMs that are treated.

Feb 21, 2018 Processing of PGM involves comminution, flotation, smelting, converting, base metals refinery and precious metals refinery. Due to increasing chrome content in the feed and the challenges associated with operating high chrome feed, alternative routes to smelting of PGM are being investigated. Some hydrometallurgical routes have been proposed.

Cobalt contained in and smelted with copper concentrate is oxidized along with iron during the final conversion to blister copper. It then enters the slag layer, which can be treated separately, usually in an electric furnace, and the cobalt recovered by reduction with carbon to a copper-iron-cobalt alloy. In nickel smelting, most of the cobalt is recovered during electrolytic refining of the nickel by precipitation from
