the process of washing chrome ore
How do we extract minerals?
Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.

CHROME WASTE WASTEREATMENT
Chrome Waste Treatment Process Chromate waste rinse water is typically treated in 2 stages. Stage 1 changes hexavalent chromium (Cr+6) to trivalent chromium (Cr+3). Trivalent chromium freely bonds to hydroxide in Stage 2 of the treatment process. The final result is a non-toxic precipitate: chromium hydroxide Cr(OH) 3.

Chromite Ore
Chromite ore is usually a combination of spinels with associated minerals such as calcite, magnetite, talc, serpentines and uvarovite. Chromites crystals exhibit an octahedral structure similar to magnetite. The Cr 3+ ions are in the octahedral position with oxygen. The chromium rich phase is antiferromagnetic.

Guides For High-sulfide Gold Processing
High sulfide gold ore refers to a certain gold ore with 20% -30% of gold wrapped by sulfide (mainly pyrite). Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold, when using direct leaching process, the consumption of gold leaching agent and cost of gold leaching production will increase, and gold processing efficiency is not good.
