chromite in the tailing, etc.) of the benefi-ciation circuit. The ROM ore properties (size distribution, grindability, liberation, physical properties, etc.) vary significantly between the different ore layers (northern band and mid band). So it is necessary to revisit and optimize the existing grinding circuit based on the ore characteristics.
of the chromite ore beneficiation plants in Sukinda region treat selected rich ores with rejection of huge quantities of low and sub-grade ore (10-38% Cr203). Beneficiation is mostly limited to crushing, grinding, desliming and hydrosizing to produce a concentrate of about 50% Cr203 with a yield of about 25-35%.
Chrome ore usually exists in the earth's crust in the following forms: chromite, which is a dark, black-to-brown-black mineral composed of chrome, iron, and oxygen. It has an affinity for oxygen and iron, so the minerals with industrial value are generally chrome-magnesium spinel or chrome-iron spinel.

to subhedral grains of chromite and quartz grains (Fig. 2b) with minor amount of Cr-Mica (fuchsite) and kaolinite. Fine dusts of chromite within quartz (Fig. 2c) and micron size quartz/silicates within chromite grains (Fig. 2d) are ubiquitously observed, which inhibits easy liberation dur-ing its processing. XRD pattern of the chromite ore shows

overall chrome ore demand significantly. China plays a significant role in the world's ferrochrome production, contributing around 36% of the total in 2014, followed by South Africa, Kazakhstan, and India (Figure 1d). Chromite ore scenario – India India ranks third in the world in chromite production, and fifth in terms of ore reserves.
Since the width of chromite ore body typically varies from 2–8 ... If the plant is a simple ore beneficiation (crushing followed by screening), then major cost part of the total processing is mining and logistics and this can vary enormously, from only a few tons of ore to well over high-tonnage operations. When the deposit is of higher ...
Among more than fifty kinds of chrome minerals found in nature, chromiteis the sole commercial source. The chromite ore is concentrated in South Africa, Zimbabwe, Kazakhstan, Russia, Finland, India. South Africa is the major chromite ore supplier. Chromite is weekly magnetic. Its density ranges in 4.1~4.7g/cm3, it…
The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 3:1 or over, 17.6 pct having a ratio between 2:1 and 3:1, and 30.4 pct having a ratio less than 2:1. Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1.
Crushers: Crushers are used to break down large chunks of raw chromium material into smaller, manageable pieces. Jaw crushers, cone crushers, and impact crushers may be employed based on the specific …
The primary jaw crusher is for crushing big rock chrome ore to a smaller size, output material to go next fine crushing machine cone crusher. The cone crusher is crushed rock chrome to below 20mm that is suitable feed to the ball mill but firstly will go to a vibration screen for screening out oversize+20mm and sent back to cone crush crushing ...
pellet with suitable cold handling strength from a chromite ore is difficult. Also, the crushing of raw materials for pel-letization and the subsequent firing of the green pellets for strength development is an energy-intensive and complex process. In contrary, sintering of friable chromite ore can be done directly without any grinding.
