The leaching of copper maximum in a sample was in the order of leaching of copper in three ores is as Sample C>sample D>Waziristan chalcopyrite. The experiments showed that the untreated raw oxidized copper ore show significant leaching which is % for saline and % for fertile soils respectively.
Ore from Hoyle Pond is processed at the existing Dome mill. Gold is recovered using a combination of gravity concentration and cyanidation techniques. The circuit consists of primary, secondary and tertiary crushing, rod/ball mill grinding, gravity concentration, cyanide leaching, carboninpulp gold recovery, stripping, electro winning and refining.

Our mills run the ore through ball and rod mills to reduce it to the proper size for our flotation process. Flotation separates the copper, zinc and lead. After separation, the various concentrates are dried to the consistency of a damp powder before being stored in our enclosed storage and shipping facility.
gold ores can be classified into 11 types (Table 1). Some metallurgical impliions to these gold ore types are summarised below: Placers, quartz vein gold ores and oxidized ores: Generally, placers, quartz vein gold ores and oxidized ores are freemilling and gold can be recovered by gravity and/or direct cyanide leaching.
