Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide. Heap leaching is one of several alternative process methods for treating precious metal ores, and is selected primarily to take advantage of its low capital cost relative to other methods. Thirty-seven different heap leach operations with a total production of 198 tonnes of gold per year (6,150,000 ounces ...
Project: INNOVAT Case Study – 10,000 t/d Heap Leach – Panama . This memorandum presents an economic comparison based on a 10,000 t/d heap leach operation located in Latin America. All assumptions, equipment layouts, mining, and costing, for the purposes of this comparison, have been accepted from the pre-feasibility base case and have not
leaching of high-grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost. In 1968 the tonnage of high-grade oxide ores was decreasing and vat leaching was on the decline. The second process, heap and dump leaching of low-
Recovery of Copper by Solution Mining Methods 3 Supplementing production from conventional heap leach operation, the in-place rubble leaching project at Silver Bell is estimated to recover 20 to 25% of the contained copper. The relatively low recovery achieved by this method is most likely due to the presence of insoluble hypogene

May 14, 2018· The estimated 17 year life of mine includes 118.7 million tonnes of mineralized leach pad feed plus 163.4 million tonnes of waste rock resulting in an average waste:process feed ratio of 1.38:1. The average life of mine leach pad head grade is 0.43% copper. The leach material placement is planned at an average rate of 20,000 tonnes per day.
heap leach pad design H eap leaching has been applied to a number of different ores containing metals including gold, silver, copper, nickel, zinc and uranium. The ore can be processed as coarse rock, normally referred to as a dump leach, or as a crushed ore in a heap leach. The reagents used and the chemistry of leaching are metal
