grade of gold in an ore [4] [6]. Cyanide bottle roll test, on the other hand determines the free gold content in the ore [4]. Sodium cyanide (NaCN) solution was used as the lixiviant in leaching the free gold from the ore into the solution. 24 hour cyanide leaching test was conducted on the sample to determine its free gold content [1] [7]

Gold grade measures the amount of gold within ore before it's processed, while gold purity refers to the percentage of gold in the final, refined product. Gold purity is either measured in fineness (the number of parts gold per 1,000 parts) or gold karats, where 24 karat gold is deemed pure.

For example, the ore I'm now working with is a mix of quartz/hematite/pyrite and is very friable. The free gold liberates at 80 mesh, down to about 20 micron. Most of the micron gold is associated with the pyrites, and lab testing has determined fine grinding to 200 mesh will liberate the pyrites to achieve a +90% gold recovery.
