The cleaner concentrate obtained by tabling the 5- and 6-pct-Cr2O3 ores from the Seiad Creek area in northern California contained from 47 to 49 pct Cr2O3 with a chromium-to-iron ratio of 1.9:1 to 2.0:1. The recoveries from both these ores were low, but the concentrates are suitable for metallurgical and/or stone use and the grades compare favorably with those of imported chromite.

in BROY 4 and in the three subsequent mills; the ball composition is a cast, high chromium alloy, consisting of 18% Cr. Analyses of the Cu rougher concentrate from the Mill scale-up program revealed that there is considerably less Zn (sphalerite) reporting to the roughers relative to that reported in the laboratory testing IMPC 2016: XXVIII International Mineral Processing Congress Proceedings
The flotation of the following metals was reviewed: copper, zinc, nickel, lead, iron, chromium, arsenic, gold, and others. The bubble generation method could be applied for typical dispersed-air
chromium flotation optimization. Palmer 1972 Palmer Fuerstenau and Aplan 1975 and Fuerstenau and Palmer 1976 have demonstrated the importance of the presence or absence of charged metal hydroxy species in such flotation These species appear particularly to influence anionic flotation of chromite when the mineral is being floated above its point of zero charge PZC
The chromium concentrate tails were also leached to remove any nickel sulfide not separated during flotation. The chromium sulfide concentrate was roasted to the oxide in a fluidized-bed roasting system. A chromium oxide product containing 0.02 percent sulfur was produced.
This invention relates to the beneficiation of chromium ores, and more particularly to the production of a chromite ore concentrate. Heretofore, attempts have been made to beneficiate chromium ores by magnetic separation, gravity concentration, and flotation methods but in the case of gravity or magnetic methods very expensive equipment is required and the flotation methods have not been
TRITHIOCARBONATES FOR PGM FLOTATION 169 Introduction An increase in the beneficiation of UG2 ore is central to Impala Platinum’s strategic plan for increasing its platinum production in 2006/07.

concentrate suggesting that mechanisms other than entrainment can be responsible for the chromite recovery. It is believed that certain reagent suites and in particular the addition of copper sulphate prior to collector addition could cause the chromite to be hydrophobic and hence amenable to true flotation (Wesseldijk et al. 1999). The presence of chromite in the concentrate can result in

A novel process for the extraction of iron, titanium, vanadium, and chromium from high-chromium vanadium-bearing titanomagnetite concentrates is proposed. This process involves several steps: partial reduction of the concentrates, magnetic separation, hydrochloric acid leaching of the titanium-bearing tailing, and alkaline desilication of the HCl leach residue. The partial reduction ensures
The stibnite flotation concentrate sample from Tiger Reef Mine, Zimbabwe, contained about 70% Sb 2 S 3 with relatively small amounts of pyrite (1.4%), arsenopyrite (1.8%) and chalcopyrite (0.4%). The concentrate was both gold (68.6 g/t) and silver (26.5 g/t) bearing and refractory to conventional cyanide leaching of these precious metals. A bulk sample of iron shavings was collected, washed
