During leaching, dissolved REEs precipitated as RE oxalates and were collected with the solid residue (gangue). Oxalic acid 0.8M, S/L: 0.1, pH 1 for 72 hours are optimal values at 25°C.

Herein, the room-temperature sulfuric acid leaching of copper smelter slag powder in the presence of potassium dichromate was investigated, resulting in the selective extraction of copper with its separation from zinc and iron. To enhance the extraction of copper, mechanical activation in the planetary ball mill and attritor was used.for the sulfuric acid leaching tests. The MS was ground in a planetary ball mill to a D90 value of less than 20µm before use. D90 is the diameter at which the cumulative distribution accounts for 90% in the particle size distribution. High purity sphalerite produced from Osarizawa mine in Akita prefecture was also used for comparison.

Effect of Ball Mill Parameters' Variation on the Particles of a Mechanical Activation-Assisted Leaching: A Hydrometallurgical Mechanics ... The first one was direct acid leaching process with H ...Nevertheless, when the leachate was strongly acidic, the leaching concentrations of HMs in the treated soil were close to the untreated soil which indicated that the anti-acid ability of soil has not significantly improved after ball milling. Low leaching behavior of HMs was observed at slightly acidic to basic pH 6–9 in treated soil so the ...
