Free Milling Gold Laboratory Testing

Friends often ask how accurate the work of our little stamp-mill is, or express the opinion that a little mill cannot do good work. As a reply we would like to place on record the results of a few tests. There are two periods of work in our laboratory; the fall term, when the class collectively goes through all our chief laboratory-processes, and the spring term, when the students work up

Refractory Gold Mining SGS

SGS has developed a series of testing and mineralogy assessment protocols that allow us to determine the character of refractory gold and the mass balance between refractory and free-milling gold. Once the deportment or textural associations of the gold is determined and the mass balance known, flowsheet options are developed.

Milling of Amenable Gold Ores SpringerLink

The objective of milling gold ores is to extract the gold for the highest financial return. To recover the maximum amount of gold, the ore must be finely ground in order to liberate the gold particles for gravity separation and/or chemical extraction. Ores yielding acceptable gold recovery (more than 88%) when “normally ground” (60–75%
