The results showed that the ultrafine flotation is an economical alterna tive if the improvement of the recovery in the mineral sector is concerned. Ultrafine flotation can also be assessed when dealing with reduction and treatment of effluent discharged in the environment. Keywords Flotation Iron Ore Slimes .
The exploration of iron ore in small mining companies results in a large amount of unrecovered fine material, representing 35 of the run of mine. Millions of tons of useful minerals are discarded every year into tailings, incurring operation costs, raising production losses and environmental impact. In addition to the disposal of 300 t h of this material, millions of tons are already stored.
PH values in levels usually applied in the reverse flotation of iron ore, i.e. between 8.9 and 11.0. The results presented in Figure 6 show that the rise in pH led to a significant rise in the recovery of Fe in the concentrate. The content of SiO 2 diminished for pH values up to 10.5 and the Fe content remained practically stable throughout the range studied.
Chrome Ore Mining Process. Chrome ore deposits are mined by both underground and surface techniques. most chrome ore must be processed by the chrome ore processing plants. the mainly chrome ore beneficiation method is gravity separation. so the mainly used chrome ore concentrating equipments are ore washbox (sometimes it is called jigger.

US20090074607A1 Process for recovering gold and silver . The present invention is directed to flotation of refractory gold sulfide ores in which the In many appli ions, a stainless steel mill with high chrome grinding media Higher froth recovery in the flotation cells is normally required to maximize.
Flotation performance was evaluated using the relationship of mass to water recovery as well as the chromite recovery. Experimental details The ore The UG2 ore was obtained from the Bushveld Igneous complex in the North West province of South Africa. The UG2 ore consists mainly of chromite at a composition of roughly 26 by mass.
3.1 Chrome magnetic separation process. The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite.
Plant. It was established that recovery of copper and cobalt from this ore with hydrometallurgical treatment is not economical, so using flotation to increase the concentration of copper and cobalt was chosen. When flotation of the oxidized copper ore was performed under standard operating conditions in the plant, good results were not obtained.
The fine grained chromite tailings of low grade can be recovered by flotation method.The solution is suitable for processing various chromite such as magnochromite, ferromagnesite chromite, magnesium iron chromite and ferrochromite. Feature. Appropriate use of gravity separation and recovery of ferrochrome concentrate by stages.
Recovery of lead and zinc by sulfide flotation carrier flotation is a common technology to improve the flotation recovery of ultra fine ores. In this study, coarse polystyrene was used as the carrier to improve the flotation recovery of fine smithsonite. Sodium oleate was used as collector to improve the flotation recovery of fine smithsonite.
Kazchrome achieves chrome tailings flotation breakthrough. Engineers at the Donskoy Ore Mining and Processing Plant of JSC TNC Kazchrome, in Kazakhstan, have successfully completed trials of a first of its kind industrial flotation technology to increase the enrichment of chrome oxide bearing tailings, Eurasian Resources Group reports.
The chrome occurs in the ore as a chrome spinel with iron oxide and only melts at temperatures exceeding milling and “secondary rougher cleaner flotation, on the existing plant tails (MF2 type circuit Figure 4). plant and at the same time attempt to improve recovery at acceptable chrome content in final concentrate. This prompted.
The ‘grade recovery’ curve. It is preferable to prepare this curve with grade on the x axis because frequently the flotation concentrate grade is set or controlled by smelter contracts. If gold were the desired metal, grade is typically recorded on the y axis, as gold recovery by flotation often depends on the recovery of ano ther mineral.
