In heap leaching the ore is usually heaped as it comes from the mine without any breaking on crushing treatment. Frequently, pieces of rock 5 or 6 feet across a face are found in the heaps. Solution is added to the ore at the surface and seeps downward by gravity and is collected in a solution sump.
The gold ore has a high mining value, the gold processing technologies are more complex, and the gold processing equipment used is not the same. At present, the common gold processing technologies mainly include the cyanide leaching method, flotation method, and gravity separation method. That is, through the crushing, screening, grinding, and classification, the ore […]

Optical sorting and lasers are very well suited to the detection of ores with different colours, such as copper oxide, or crystalline structures in quartz. By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations.
2.7.4.1.1 Copper Ore Heap leaching. The extraction of copper from ores by hydrometallurgical methods involves leaching. Almost exclusively, leaching is performed on heaps of materials. Heap leaching is conducted on ore stockpiles (traditionally called dump leaching) to static heaps to on–off dynamically loaded pads.
Crushing: Facilitates flow of sticky material through the circuit by washing/screening of fines and delivering them to the leach feed tanks. Milling: Produces ore slurry of desired particle size by milling of crushed ore , where required, from crushing section.
Reducing Acid Consumption of Low Grade Oxide-Sulfide Copper Ore and operating costs and simple atmospheric leach process make heap leaching suitable for low grade ores and small deposits. Disadvantages include low recoveries, long ramp-up times, large footprint and acid-mine drainage of wastes [6].
Copper is one of the most useful metals .Copper ore beneficiation is a process to extract copper from raw ores. Copper ore is an ore which can produce copper metal by crushing it in ore crushing plant, grinding it in Ball mill and then smelting it in a furnace along with a piece of tin ore.

Heap leaching is a process extensively used by the mining industry to recover metals from large quantities of submarginal grade materials. Currently, heap leaching finds important applications in the recovery of copper from its ores because of its low cost, short construction time, operational simplicity, good
Copper is extracted from ore by crushing copper bearing ore followed by heap leaching with sulfuric acid and then moving the resulting solution to a tank containing scrap iron and agitating the solution to precipitate the copper.
Ore from the primary crusher will be scrubbed ahead of secondary and tertiary crushing to remove clay associated with the ore. The scrubber will be equipped with a trommel screen and oversize material from this screen will be crushed using an open circuit secondary impact crusher while trommel undersize will be wet screened on a double deck screen.
The heap leaching unit corresponds to a copper ore heap of 456,000 m 2, with a grade of 1.5 % of copper. Also, the time horizon corresponds to 360 days and copper price was considered to change from 2,000 to 12,000 $/ton.
Dump leaching can be considered as a subset of heap leaching, because this avoids sophisticated and costly ore crushing and designed heaps, since ores are staked in over 18-m piles without an advanced configuration and design [23,24,25,26]. As in heap leaching, after collecting percolated solution in the drainage system, SW-EX is applied to
Crushing-Desliming-Leaching The raw material for the production of copper cathodes is the copper bearing ore, which is extracted from the Phoenix mine. This ore contains 0,1 % to 0.5% copper. Depending on the copper content the ore is separated into two products, a high grade ore and a low-grade ore. removed. This material is
The leaching reagent (dilute sulfuric acid) is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap, where it dissolves the copper from the ore. The resulting “pregnant” leach solution of sulfuric acid and copper sulfate is collected in a small pool.

Copper is processed in several stages from extraction and crushing of the ore to electrolytic refining, which allows obtaining 99.99% pure Copper Cathodes. The beginning for all copper is to mine sulfide and oxide ores through digging or blasting and then crushing it to walnut-sized pieces.
dissolution of copper oxide ore. ratio of 10 mL/g is found to be optimal for leaching of copper using H2SO4. This can be explained in a way that the leaching agent is in excess of the calculated amount for the extraction of copper. After 75 min of dissolution, the amounts of copper extracted from the oxide ore were 57.37, 74.73, and 66.71% at L
case for testing the possibility of leaching the copper tailings. The ore used,was a low grade copper tailing. The are is highly si1icous, which fact is favorable to leaching, as the Si02 does not interfere with the re actions between the copper in the ore and the solution. The screen analysis of the ore is as fol10ws;-On 80 mesh =

0.3% Cu for copper oxide ore) or strong leach solution (pH of copper sulfide ore leach solution is 1.1 and pH of copper sulfide ore leach solution is 2). Column leaching results also show that about 80 to 90% of copper was recovered from the copper sulfide ore in a very short leaching time irrespective of crushing technique.
