Large tonnages of chromite tailing were discarded during processing of chromite ore in the conventional circuit. A typical chromite plant tailing was treated in wilfley table for the recovery of chromite values. Optimisation study was carried out for the process parameters of wilfley table using empirical models, developed from the experimental …

Most of the ore mined at the Donskoy Ore Mining and Processing Plant is supplied to ferroalloy plants in Aksu and Aktobe. Ore with a high chromium oxide content (up to 62% Cr 2 O 3) is used to produce ferroalloys in metallurgy, as well refractory products, and chromium compounds in the chemical industry. The Donskoy Ore Mining and …

Chromite ore processing residue (COPR) is a waste byproduct of chromate production that contains high levels of hexavalent chromium (Cr(VI)). Although the high temperature chromite process was banned in several countries, its legacy still exists at numerous contaminated sites. For instance, New Jersey alone has over 2 million tons of waste …
