1. The compositions of the South African chrome ore are relatively simple, chromite is the main mineral, and accounts for more than 91%; chlorite and forsterite are the main gangue minerals. The main elements in the pyrite are Mg, Al, Si, O and a small amount of Fe; the main elements in the forsterite are Mg, Si and O; 2.
The global Chromite Ore market size was valued at USD 8859.99 million in 2022 and is expected to expand at a CAGR of 6.61% during the forecast period, reaching USD 13009.94 million by 2028.
The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron …
Experimental studies were carried out on the reducibility of two different chromite ores using different reducing carbonaceous reducing agents in the temperature range 1173 to 1573 K. "Friable lumpy" ores and "hard lumpy" ores were used in the experiments. Petroleum coke, devolatilized coke, (DVC) and graphite were used as reducing agents.
In the ore, 97.87% Cr and 97.13% Fe are rich in chromite. There are a small amount of Mg, Al, Si existing in the chlorite, Mg and Si are main composing elements in the forsterite in Table 6. The existing forms of elements in minerals are usually divided into three [ 14 ]: micro inclusion, isomorphism and ion adsorption.
