Ore processing facility: ore would be reduced in size to fine particles by crushing and grinding, then flotation would separate the goldbearing sulfide minerals from non mineralize rock. The floated material would be treated using pressure oxidation technology in autoclaves, and the gold would be recovered from the floated material in a carboninleach (CIL) circuit.

· The sourced ore is processed through a centralised processing facility with a nominal annual capacity of 7Mtpa, producing between 180,000oz and 200,000oz of gold a year. The processing circuit comprises single stage crushing, semiautogenous grinding, gravity recovery, flotation, regrind and carboninleach recovery (CIL) to extract gold.

Gold mining is the process of mining gold ores from the ground up till the stage where pure gold is extracted (Richiewiki, 2010). The gold ores are usually big and. have to be crushed to reduce them to a size of about 12mm diameter before pure gold can be extracted from them. The ore usually has to pass various crushing stages, each

African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically 80% passing 75µm) to ensure that all nonrefractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the ...

Gold is the most malleable of all metals. It can be drawn into a wire of singleatom width, and then stretched considerably before it breaks. Such nanowires distort via formation, reorientation and migration of disloions and crystal twins without noticeable hardening. A single gram of gold can be beaten into a sheet of 1 square metre (11 sq ft), and an avoirdupois ounce into 300 square feet ...
