Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …

The Gedabek mine is a conventional open pit, truck and shovel operation, with a current mining rate of about one million tons of ore per year, resulting in an annual gold production of approximately 50,000 oz. Rock breakage is accomplished by blasting, which is carried out once per day.Blast holes are drilled on a 2.5 m × 2.5 m pattern in ore and 3 …

Heap Leaching Flow Chart Incorporating Agglomeration into the Heap Leaching Process. The agglomeration of the fines in the heap leaching process allows for enhanced, even percolation of a heap. If left untreated, smaller fines can accumulate in the spaces between larger particles, inhibiting flow of the leaching solution (see figure 2).

This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution. The gold attaches to the carbon and is pulled from the solution. We then "strip" the gold from the carbon by washing it with a caustic cyanide solution. The carbon is later recycled.

The new ore bodies are estimated to deliver 5.8 Mt of ore with a gold grade of 0.78g/t and 0.38% copper. The mining process typically involves the recovery of broken rock from the draw points by 14t capacity electric and diesel-powered LHDs (load, haul, dump) loaders, which send the ore to a primary crushing station, consisting of a plate ...

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.
