Summary: This study proposes a novel process to simultaneously extract valuable metals from low grade nickel matte through oxidative leaching using a mixed solution of (NH4)2S2O8 and H2SO4. The effects of factors such as matte particle size, stirring speed, leaching time, leaching temperature, mass ratio of ammonium persulfate to matte (A/M), and sulfuric acid concentration on metal extraction were investigated. The study also explored the addition of saturated ammonium persulfate solution to improve metal extraction. The optimal leaching conditions led to extraction rates of 91.8% for nickel, 96.1% for copper, 96.6% for cobalt, and 66.9% for iron.

Summary: This study develops a hydrometallurgical method for concentrating nickel from laterites using long-term oxalic acid leaching and size separation. The results show that nickel initially dissolves and then precipitates with the presence of oxalate ions, while iron steadily dissolves and remains in solution when protected from light. The leach residue is separated into fine and coarse fractions, with accumulation of nickel in the fine fraction yielding a concentrate. The proposed method has the potential to exploit low-grade nickel laterites.

Summary: In this study, vanadium (V) was found to enhance the removal efficiencies of impurities in metallurgical-grade silicon (MG-Si). The addition of V increases the difficulty of acid etching for the precipitated phases in MG-Si, mainly due to the low acid sensitivity of Si2V phase. The formation of Si2V phase also contributes to the increased removal efficiency of boron (B) in the Si-V alloy.

Summary: A first principles model is developed to describe the dissolution mechanism of phosphate ore particles in a solution of phosphoric acid. The model accounts for non-uniform size of ore particles using particle size distributions and quantifies their influence on the model predictions. A global estimability analysis is carried out to determine the estimable parameters from experimental data, and the predictions show good agreement with the experimental data. The computed activation energy indicates that diffusion is the rate limiting step of the dissolution process.
