field weight. Processes for removing the debris and almond hulls and shells are potential sources of air emissions. Process Description17 After almonds are collected from the field, they undergo two processing phases, postharvest processing and finish processing. These phases are typically conducted at two different facilities.

The electrolytic process (Wohlwill process) involves dissolving gold from the bullion (anode) in a chloride solution and redepositing the gold on a pure gold or titanium hode. Silver remains on the anode. The hodes are melted and cast. In the third process the unrefined bullion is dissolved in aqua regia and silver is precipitated as ...

The average length of the hole drilled was 900m with the deepest hole being 1,090m. Ore processing. Ore mined is treated and smelted at Mponeng's gold plant. The ore is initially ground down by means of semiautogenous milling after which a conventional gold leach process incorporating liquid oxygen injection is applied.

These bars are a semipure alloy of gold, usually about 90% gold. They're then refined into pure gold. The ore processing facility – also known as The Mill – includes processing facilities, chemical storage facilities, spill containment structures, a water treatment plant.
