Leaching Fine Gold Mineral Processing amp; Metallurgy

Many definitions of the word slime have been attempted to Leaching Fine Gold but the one that best expresses its meaning from a practical point of view is that given by Park that it is that part of the pulverized ore that is not percolable on a commercial scale without the use of pressure. The consequences of this definition are that slime cannot be treated commercially by the same
