Effect of Particle Size and Grinding Time on Gold

The effect of particle size on the dissolution of gold is usually studied using mono size particles as the gold in solution comes from the ore of a unique leached particle size This paper proposes a method to estimate the gold dissolution as a function of particle size using a bulk ore sample i e with the dissolved gold coming from the various sizes of particles carried by the ore …
