 · The excess acid from the autoclave process will be used to make up the acid demand for associated copper ore heap and dump leaching operations INTRODUCTION The recovery of copper from ores is dominated by the flotation of copper concentrates followed by smelting—converting and electrorefining This process has been enabled by the development of froth flotation and progressively

Bacterial ore leaching can be applied to extract heavy metals from low grade ores industrial wastes and other materials on an industrial scale by different procedures dump leaching in situ leaching tank leaching leaching in suspension Sulfidic copper and uranium ores are the principle ores leached in several countries So 20% to 25% of the copper production in the and about 5% of

 · The excess acid from the autoclave process will be used to make up the acid demand for associated copper ore heap and dump leaching operations INTRODUCTION The recovery of copper from ores is dominated by the flotation of copper concentrates followed by smelting—converting and electrorefining This process has been enabled by the development

Heap leaching a process by which metals such as gold and copper are recovered from ore has long been a method of choice in ore beneficiation with applications growing all the While this process has proven to be efficient often chosen for its cost effectiveness the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum

 · Copper heap leach development not as easy as it looks Heap leaching has become increasingly popular in the copper industry for treating oxide and

Leaching under high pressure was performed in special devices autoclaves Slurred crushed ore from the mine is conveyed to the processing plant to be pressure leached with sulphuric acid The High Pressure Acid Leaching HPAL area receives the slurred feed heats it up to 225 270°C and mixes it with hot concentrated sulphuric acid inside

Hari om you are asking a question as to How is copper extracted by Hydro metallurgy from low grade ores Hari om ANSWER Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals with the remai

The pilot plant was built in the Gobi Desert The six heaps operated well at heights from to m Detailed investigations of the permeability copper leaching rate acid consumption and water evaporation showed that heaps of − 40 mm ore leached for 68 days produced a copper leaching Cited by 11 Experimental studies and pilot plant

Heap leaching starts with the sprinkling of a low concentration sulfuric acid and water solution on a stockpile leach pad of low grade ore The liquid percolates through the stockpile and dissolves copper minerals producing an approx 60% copper

Most copper bioleaching plants operate with a high concentration of sulfate salts caused by the continuous addition of sulfuric acid and the recycling of the leaching solution Since the bacteria involved in bioleaching have been generally isolated at low sulfate concentrations the bacterial population in ores leached with the high sulfate solution M employed in a copper

Pine oils cresylic acid and long chain alcohols are used for the flotation of copper ores The flotation concentrates are then dewatered by clarification and filtration resulting in 10 to 15 percent water 25 percent sulfur 25 percent iron and varying quantities of arsenic antimony bismuth cadmium lead selenium magnesium aluminum cobalt tin nickel tellurium silver
