4 ·UG2 tailings is the material left after the PGMs have been extracted from the UG2 ore through a floatation and concentration process The UG2 tailings have low Cr Fe ratios and chromite content compared to conventional Lower Group LG and Middle Group MG chrome ores which are the conventional chrome bearing ores mined in South Africa
·Chromite mining ores serve as a major source of chromium production Other occupational exposures to chromium typically occur in the production of stainless steel as well as chrome plating and tanning industries While nasal mucosa irritation and considerable sneezing can be caused by breathing in Cr
·The focus of the work is to highlight the present environmental and social impacts of extensive mining on the health of the common people of Odisha The mining activities have created havoc impact to the environment and social life of the state Odisha has huge deposits of ores and minerals of chromite nickel bauxite iron coal copper manganese
·The recent identification of chromite deposits in two districts of Manipur Ukhrul and Chandel has led the government to grant mining clearances disregarding constitutional provisions
·As part of a broader programme to fully characterize the chromite ores discovered in the Ring of Fire region of northern Ontario NRCan and private research facilities in Canada have
·Ore texture refers to the morphological characteristics reflected by the morphology size and spatial combination relationship of mineral crystal particles in ores including the combination between crystal particles in ores and different mineral aggregates in ores For example chromite in disseminated chromite ores mostly shows idiomorphic
·The optimum operation parameters determined for the concentration of chromite ores are as follows; a washwater flowrate of 3 1/min shake amplitude of 15mm shake frequency of cps tilt angle
·around million tons of chromite ore per year Das and Mishra 2010; Dhal et al 2011 Widespread contamination of the valley due to excessive mining of chromite ores has made it to be considered as the fourth most polluted place in the world Blacksmith Institute report 2007 The chromite mine of TISCO in the Sukinda valley is the largest open
The extraction technology for platinum group metals PGMs has changed dramatically in the last 80 years and the changes are likely to continue for years to come This article will review advances in PGM extraction including developments in semi autogenous and fully autogenous milling; flotation equipment applications for treating high chrome ores; increases in power
·During mining and processing operations enormous quantities of fines are generated which are of major concern from handling storage and environmental point of view Since most chromite ores are easily beneficiated with gravity concentration methods flotation of chromite has not been widely applied or got commercial acceptance Atalay and
·Chemical grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium to iron ratio of 1 to 2 1 Refractory grade chromite ores contained a minimum of 20 pct Al2O3 and more than 60 pct Al2O3 plus Cr2O3
