Ore Treatment an overview ScienceDirect Topics

Ore Treatment Mineral processing comprises two principal steps: size reduction to liberate the grains of valuable mineral (or paymineral) from gangue minerals, and physical separation of the particles of valuable minerals from the gangue, to produce an enriched portion, or concentrate, containing most of the valuable minerals, and a discard, or tailing (tailings or tails), containing predominantly the gangue

Long-term treatment issues with chromite ore

2007-5-17  A pugmill treatability study was conducted to remediate chromite ore processing residue (COPR) using ferrous sulfate heptahydrate (FeSO 4 ·7H 2 O) as a reductant. Two different types of COPR, with respect to particle size and mineralogy, were tested in this study. Two different stoichiometric ratios of FeSO 4 ·7H 2 O to Cr 6+ (5× and 8×) were

Processing of refractory gold ores ScienceDirect

1991-1-1  The best choice of a processing route to treat a refractory ore will in most cases be site specific, due mainly to the metallurgical and mineralogical characteristics of the ore. The successful application of these processing techniques can result in mining operations that would otherwise have been impossible.
