CNLITE Eco-friendly Gold Leaching Reagent

Dosage: The dosage of CNLITE gold dressing agent can refer to the dosage of sodium cyanide. Its dosage is about 0.5 to 1.0 parts per thousand (500-1000g of reagent/ton of ore). The actual dosage should be calculated based on the concentration of the slurry. Also the property, grade of the ore and pH of the slurry also can affect the dosage of CNLITE gold dressing agent.

The Metallurgy of Cyanide Gold Leaching An Introduction

20/10/2014· Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed i.e. the gold is liberated.

How is Sodium Cyanide Consumed during Gold

The cyanidation plants has been using sodium cyanide to dissolve the gold from the ore in order to recover the gold from the leaching solution. The formula is as follows: 2Au+4NaCN+O2+2H2O→2Na[Au(CN)2]+2NaOH+H2O2. 2Au+4NaCN+H2O2→2Na[Au(CN)2]+2NaOH. From the electrochemical reaction, it can be known that dissolving 1 gram of gold consumes 0.92 grams of sodium cyanide. 2.Cyanide

4 Reasons and Solutions of Poor Gold Leaching Effect

Reason #3: There are cyanide-consuming minerals such as copper and zinc in gold ore. Some gold ores are accompanied by copper and zinc minerals, such as malachite, azurite, pyrocopper and sphalerite (especially oxidized sphalerite), etc., which have high solubility in cyanide solution. While leaching gold, they will “compete” with gold for
