The basic premise of this process is simple: gold ore is crushed and ground as fine as possible, then combined with a solution of cyanide which leaches the gold out of the ore. Later iterations of the MacArthur-Forrest Process oxygenated the cyanide mixture to increase the rate at which cyanide leached gold from the solution.
