The IsaMill goes global (2003– ) The initial development of the IsaMill was driven by problems encountered treating MIM's lead–zinc ore bodies. The next major leap was driven by problems experienced by South Africa's platinum producers, driving the development of larger mills and initiating the global penetration of the technology.
Following extraction, ore goes through crushing and grinding stages and appropriate size ore particles are then fed into the cyanidation process, which is responsible for extracting gold from the ore. Sometimes, further concentration of the ore is required (e.g. if sulphides are present) and flotation stages are then included.
local coal, calamine (zinc bearing ore) from the Mendips and copper ore from Cornwall into the site. Before William's time, in Europe, only poor quality brass was made.
