Increasing the pH value does not affect the gold leaching rate significantly for the mixed lixiviant system. What is observed is the gold leaching rate for pH 1.5 is a little higher than that for pH 1.0 and 1.9. In the thiourea only solution, a high pH value is favorable for gold dissolution (Li and Miller, 2007).
leaching produces 12% of the world's gold. Heap leaching for silver is conducted using the same principles and operating practices as for gold, but heap leach operations produce only a small fraction of world silver production. INTRODUCTION Heap leaching had become a fairly sophisticated practice at least 500 years ago. Georgius

Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributorsthe overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of well mixed neutralized sand, ample contact with strong and weak
LEACHING SlamJet sparging is the most cost effective injection system for leaching processes The Process In the cyanidation process for gold ores, metallic gold must form a cyanide complex during the process of dissolution according to the following reaction
Gold heap leaching. Heap leaching is an industrial mining process to extract precious metals, The mined ore is usually crushed into small chunks and heaped on an impermeable plastic and/or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals.
Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide quot;vat leachingquot; mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in
A high gold extraction (over 95 per cent) is achieved on cyanide leaching of the oxidised residue. Mintek has developed and refined the process fundamentals of the Bacox technology, and procedures for testing the amenability of refractory gold ores to bioleaching are well established.
