2022-11-1 1. Introduction. Chromite ore processing residue (COPR) is a byproduct produced in chromite processing at high temperature (1000–1200 °C). 2.5–3 tons of lime-based COPR were generated per ton of chromium salt (calculated by Na2 CrO 4) ( Fu et al., 2021 ).

2021-1-4 Overview of chromite ore processing. Chromite ore FeO·Cr 2 O 3 is a major ore for Chromium. India accounts for about 10% of world share of shipping grade Chromium ore reserves, having 45% Cr 2 O 3 content. South Africa and Zimbabwe and India are the Top five countries of Chrome ore processing industries in the Word (Indian Minerals Year Book 2016).

2008-10-23 The pH of the leaching solutions was adjusted to cover a wide range between 1 and 12.5. The concentration levels for total chromium (Cr) and Cr (VI) in the leaching solutions were virtually identical for pH values >5. For pH values <5, the concentration of total Cr exceeded that of Cr (VI) with the difference between the two attributed to Cr (III).
