Dozens of epidemiologic studies have been conducted since the late 1940s in an attempt to elucidate the relationship between exposure to chromium compounds and increased rates of certain cancers observed in several industries. The relationship between employment in industries producing chromium compounds from chromite ore and lung cancer has been well established in numerous studies. The relati...

Chromite ore processing tailing, a solid waste generated during the of chromite ore, is difficult to recover due its ultra-fine size. The tailings from process contains valuable and iron-bearing minerals, loss which matter concern for ferrochrome industry worldwide. Tailings plant mainly dumped, causing space environmental concerns. Researchers worldwide have carried out rigorous study on recov...

Milling is a vital unit operation in various material processing operations and consumes around 2% of the energy produced in the world [1,2]. It dictates the cost economics of mineral, cement, power, pharmaceutical and ceramic industries. Grinding is an important unit operation for chrome ore pelletisation process. Chromite ore along with 5% coke is milled in the wet ball mill and filtered ore ...

The rapid development of industry increases the demand and importance chromium. In this study, beneficiation possibilities representative chromite ore taken from Tokat Province with a laboratory type jig, spiral concentrator, shaking table multi gravity separator (MGS) were investigated. Appropriate particle size fractions fed into each device. Experimental studies shown as flow chart. gave bes...

Orissa accounts for 95 percent of the chromium ore reserves of India. It increases the economic status, but adversely reduces the ecological cover. Chromite mines generate considerable quantity of pollutants containing toxic hexavalent chromium, a known carcinogen, which contaminates 10 to 4000 mg/kg (ppm) of total chromium in air, water and soil environment. Surface water and ground water in S...

the study area is located in the south of kerman province and in the esphandoghe- dolatabad zone. numerous chromite ores were found in the area that has been explored by surface outcrops. with respect to the previous exploration- exploitation works and the absence of the pilot layer, the best option was the boreholes’ drilling was the best choice in order to complete the detailed information. f...
