9 Ore Deposits and Economic Minerals – Mineralogy

After mining, processing separates and concentrates valuable minerals from the ore. This involves crushing the ore rock, followed by gravity and chemical separation. Any unwanted rock and minerals, called waste rock and gangue, respectively, are usually discarded in tailings piles. This photo (Figure ) shows tailings at a mine just south of Quebec City, Quebec. Besides .

Global – Chromite Mining and Processing Economics. The value of the mineral chromite is in its content of the base metal chromium. The value of chromium is in its industrial appliions, especially when alloyed with iron to produce a wide variety of steels that are more durable largely due to their corrosion resistance. Globally, 96% of the mined chromite is in support of the .

Extraction of Chromium from Chromite Ore

 · Chemicalgrade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromiumtoiron ratio of :1 to 2:1. Refractorygrade chromite ores contained a minimum of 20 pct Al2O3 and more than 60 pct Al2O3 plus Cr2O3. Primary chromium needs for all uses in the United States by the year 2000 are estimated to be nearly three times its present annual .

Chromite ore processing line

Chrome Ore Mining Process. Chromite beneficiation process is efficient and simple, which can achieve the best effects. The qualified materials are evenly fed into the ball mill for grinding, then chromite power is sieved by the spiral classifier. The versize chromite power return to the ball mill for regrinding. Gravity separation is the main method for chrome beneficiation. The .

Chromite Beneficiation Process

 · The Problem with Chromite Processing. Experience indies that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the ore is minus .
