This study investigated the recovery of nickel from tailings (0.2% Ni) obtained in a chromite beneficiation plant using H2SO4 leaching followed by oxalic acid precipitation. The tailings were characterized using mineral liberation analysis. Ni was found as Fe-Ni, Fe-Ni-Co sulfide minerals, which were encapsulated in serpentine, …
Chromite tailings are generated from chrome ore beneficiation plants, containing substantial quantities of ultrafine particles. Generally these ultrafine particles of chromite cannot be treated effectively using conventional beneficiation methods, because of limitations in particles size being treated by these processes.
The raw chrome ore is the tailings after floating separation of platinum and palladium, and the grade of Cr2O3 is relatively high. 【X-ray diffraction analysis】 The main mineral ores in the chrome sample are chromite, enstatite, anorthite, hopfnerite, diopside, albite, biotite, etc.. 【Physical analysis】 The metallic minerals in the chrome samples …
In the beneficiation of phosphate ores the tailings generated still carry significant phosphate content. The recovery has been difficult as the tailings carry a large proportion of clay minerals, magnesium oxide and iron carbonate mineral known …
Most of the chromite is lost to the tailings in the finer fractions (<75μm) indicating the poor efficiency of gravity concentration methods currently used in industry on finer and …
Bauxite wet beneficiation requires large capital investments in a washing plant, tailings dams, power generation, water treatment, etc. and increased operating costs, environmental licensing, restrictions on water usage and rehabilitation of tailings.
The tailing sample was beneficiated by hydrocyclone, tabling, wet high-intensity magnetic separation (WHIMS), and flotation in order to recover the chromite. A chromite …
