An estimation of the beneficiation costs of ore and upgrading cost of scrap was made and the costs were compared with the benefits. The overall conclusions are as follows: The loss of iron units in ore beneficiation is compensated for with higher savings in the EAF together with reduced consumption of slag formers.

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, …

Good beneficiation of Ps can be achieved by various processes, depending on the liberation size of phosphate and gangue minerals. Different processes like screening, scrubbing, milling, washing, calcination, leaching, and flotation may be used. Milling is an important stage in the beneficiation of low-grade phosphates.
