Roasting and Processing Sulpho-telluride ore to recover gold. This roasting plant, since closed down, was equipped with eight standard 70-spindle Edwards roasters, though only four were finally in use. Fuel was supplied to four ports on each furnace in the form of pulverized lignite of 8500 B.t.u. value prepared at a central plant.
The system also recognizes the high variability in gravity gold content in a typical processing plant feed ore over the life of project. Most discrete ore bodies tend to have reasonable consistency in their percentage and deportment of GRG.

Gold CIL (carbon in leach)processing plant is an extraction process for recovery of gold, including crushing, grinding, leaching process, etc.
Gold Ore. Gold ore mainly refers the mineral which has gold content and exploitation value. According to gold structure and content in the ore, gold ore can be classified into gold mineral, gold bearing mineral and gold carrier mineral.
In order to generate the most value from refractory gold ores and prevent longer-term distress due to grade erosion, we see three main areas for action that miners should consider: ... Another benefit of having a refractory-ore processing plant is the transfer of know-how and experience between different operations.
