Aug 03, 2019· The dump leaching of lowgrade copper ores, as an integral part of the openpit mining operations in the Southwest, has been practiced for the last fifty years and is increasing in importance as one of the major sources of copper The recent acceleration in dump leaching can be attributed to the greater tonnages of lowgrade ores mined andDump leaching is an industrial process to extract precious metals and copper from ores Dump leaching is similar to heap leaching, however in the case of dump leaching ore is taken directly from the mine and stacked on the leach pad without crushing where, in the case of gold and silver, the dump is irrigated with a dilute cyanide solution that percolates through the ore toDump leaching Wikipedia
How copper dump leaching works ScienceDirect
Sep 01, 2021· In copper dump leaching, runofmine ore is irrigated with acidic leaching solution to generate aqueous cupric ions for further processing The very large size of the ore particles being leached, as much as two meters in diameter, should preclude any significant metal recovery Dump leaching should not work; and yet it doesDump and Heap Leaching 33 LEACH PADS The leach pad itself is a key element of the heap or dump leach process Selection of the type of leach pad, detailed pad design, liner selection, construction techniques, and assessment of geotechnical risks are all part of the overall leach pad development process Types of Leach PadDump and Heap Leaching HydroJex
Copper Dump Leaching and Management Practices That
The acid strength of the leach solution varies proportionately with the rate of leaching,the grade of the copper ore leached, and the amount of acidconsuming gangue present in the ore10 The pregnant liquors produced by heap leaching are generally much higher in copper content than those produced by dump leaching because ore grades are higherthe basics of leaching tests for waste materials, current regulatory leaching tests, interpretation of leaching test results, factors influencing contaminant leaching, and uses of leaching tests for evaluating risk associated with solid waste management for decision making This document mainly describes leaching of inorganic speciesA Guide to Leaching TestsFinal
Effects of bioleaching on the mechanical and chemical
Jan 13, 2012· 高达10%返现· Mechanical behaviors of the leached waste rocks, such as failure patterns, normal stress, shear strength, and cohesion were determined through mechanical tests The results of SEM imaging show considerable differences in the surface morphology of leached rocks located at different parts of the dump
