In addition, the smectite clay employed can be either crude (containing gangue or non-clay material) or beneficiated (gangue removed). The ability to use crude clay in the smectite-type clay of this invention represents a substantial cost savings, since the clay beneficiation process and conversion to the sodium form do not have to be carried out.
A process for the recovery of nickel and cobalt from laterite ores, the process including the steps of: a) beneficiating the ore to separate it into a beneficiated upgraded ore fraction and a coarse, siliceous low grade rejects fraction which is substantially free from fines and clay materials; b) separately processing the upgraded ore fraction for the recovery of nickel and cobalt; and c ...
The beneficiation methods for some tantalite ores from selected deposits in Nigeria have been assessed through mineralogical and compositional analyses of the ores. Tantalite ores obtained from eight different well-known locations of the mineral in the country were analyzed with 109Cd excitation source Energy Dispersive X-ray spectrometry using the emission-transmission method of quantification.

Aug 15, 2018· Scheelite (CaWO 4) and wolframite ((Fe, Mn)WO 4) are the only tungsten minerals mined commercially and are mainly found in five types of deposits: skarn, vein/stockwork, porphyry, disseminated and stratabound.Gravity concentration and flotation are the beneficiation techniques most commonly applied to scheelite ore, and gravity and/or magnetic separation for wolframite ore.
Gypsum is the most common of the naturally occurring sulfate minerals. It is found in very extensive, bedded sedimentary deposits all over the world and is associated with limestones, shales and sandstones, marls and clays. High-purity deposits of gypsum are relatively common, and, for most uses, little or no beneficiation is required.
