The concentrate obtained varies in quality according to the care exercised in the various operations, but usually contains about 50 per cent, of chromite. UTILIZATION OF CHROMITE One of the most important applications of chromite ores is in the production of ferro- chrome alloys used in the making of chromium steels, which are steels containing.

In this study, segregation roasting and magnetic separation are used to extract nickel from a garnierite laterite ore. The garnierite laterite ore containing % Ni, % Co, % Fe, % MgO, and % SiO2 was collected in the Mojiang area of China.

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.

The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the.

The subject matter of mineral economics is so varied and complex, and at the same time so fascinating that one has to make an exploratory trip through the entire range of mineral industry. The study should impart to students, the idea of becoming a ‘spying agent’ for the search, mobilization, and utilization of minerals.
