Simulated small-scale pilot heap leaching of low-grade

1/12/2008· The bioleaching of low-grade copper sulfide ore and the selective extraction of copper were investigated. Lix984 dissolved in kerosene was used as extractant. The results show that it is possible to selectively leach copper from the ores by heap leaching.

Mineralogy, petrology, and chemistry studies to evaluate

15/6/2008· Heap leaching with drop emitters on the ore surface at Sarcheshmeh porphyry copper mine (looking toward the north). The exploitation of copper oxide ores was not economical in the past, but heap leaching now has the advantages of low investment, better working conditions, and lower energy consumption [6] .

A BACTERIAL HEAP LEACHING APPROACH FOR THE TREATMENT OF LOW GRADE PRIMARY COPPER SULPHIDE ORE

Whereas many heap leach operations have utilised natural convection to supply air to the heap, forced aeration has more recently been shown to reduce the residence time required to achieve around 80% copper recovery from 450 days to 200-300 days (1), (2)

Heap Solutions | Mining Geophysics and Enhanced Metal

Recently, HGI has been helping a copper heap leach facility in Arizona with its end-of-mine plans. A pilot scale injection project that included four deep rinsing wells and nine monitoring wells was tested to see if applying raffinate directly to ore under moderate pressures (i.e., rinsing) can increase liberation and eventual recovery.

Innovations in Copper Mineral Processing Technology

Reasons for Copper Ore Sorting cont. • Pre-concentrate feed into high-grade and low-grade stockpiles: – Optimize multiple process streams i.e. send ore to either mill, heap leach or smelter. – Allows smaller mills to be built or increase capacity of an existing mill.
