Chromite - ScienceDirect

Jan 01, 2016  Although the intention of chromite mining is to remove chromite from the ore for the production of ferrochrome, the process is not 100% efficient, so mining and smelting wastes including dust, wastewater, tailings, waste rock, and slag (produced during ferrochrome separation from the ore) still can contain different forms of Cr, including Cr(VI).

Chromite - Wikipedia

Chromium extracted from chromite has been used in anthropogenic processes in the past decades developing major health and environmental concerns around the world. When chromium is in the trivalent (Cr(III)) form, it is a crucial part of a balanced animal and human diet. However, its defect will cause a disruption to the lipids and glucose metabolism in animals and humans. On the other hand, when chromium is in its hexavalent(Cr(VI)) form, it is a highly toxic carcinogen and if ingested by an animal or human it

Chromite - an overview ScienceDirect Topics

Mihail I. Gasik, in Handbook of Ferroalloys, 2013 8.2.3 Chromium Ores and Chromites Processing. Chromite ores, as might many others, be mined by open-pit and underground methods. The share of underground mining varies between countries and deposits. The extracted ore is subjected to crushing and sorting (normally rich ore containing more than 45% Cr 2 O 3 is supplied to the processing plant ...
