Chromite ore beneficiation: prospects and challenges
Idiomorphic chromite is the only ore mineral appearing in economic quantities. The average content of the ore is 26% Cr 2 O 3 and the Cr/Fe ratio is 1.55. The Kemi chromium mine is an open-pit mine with a waste rock to ore ratio of 5.5:1. At Kemi, the ore from the mine contains 11% iron and 25.5% Cr 2 O 3.Molybdenum, as a strategic rare metal, has been widely used in many fields, such as alloy materials, electronic technology, chemical catalyst, aero science, and so on. It has been reported that almost 50% of molybdenum originates from the separation of Cu-Mo concentrate [1], [2], [3], especially from porphyry Cu-Mo ores [4], [5], [6].

A serious problem faced by the metal mineral mining industry is the challenge to the sustainable development of resource mining due to the continuous decline of ore geological grade. In the case of producing concentrates of the same quality, compared with using only high-grade raw ore, ore blending is a way to slow down the 3.1.5. Molybdenum mine wastewater. In molybdenum ore dressing, sodium silicate was usually added as a mud dispersant and inhibitor, and lime was used as a pH regulator, which made it difficult for molybdenum ore tailings to settle naturally and pH of tailings was alkaline.

The Prospect of Recovering Vanadium, Nickel, and Molybdenum
Black shale ore contains rich strategic metal resources such as vanadium, nickel, and molybdenum, but due to its complex composition, it is currently only used in the vanadium extraction industry. Metals such as nickel and molybdenum have not been effectively recovered, resulting in environmental pollution and resource waste.

In the process of ore beneficiation, applying open control loop systems using ore quality as input parameter, proves very effective. To determine the ore quality, on-line analysis of its materialThe ore had a head grade of 0.259% Cu and 0.0064% Mo. The ore charge of 1.0 kilogram was ground at 60% solids to 60% passing (P60) a 150 micron (100 mesh) screen. The ground ore slurry was adjusted to a pH of 10.5 with lime.
