Description
Jinchan gold leaching reagent gold dressing agent
Product Characteristics
1. Gold leaching chemicals reagent / metallic gold ore metal dressing agent — the green products with environmental protection and gold extraction (tested by authoritative departments, the products belong to ordinary goods)
2. Creating exclusive patent in the world (the only brand of environmental protection withdrawal gold, the only patent in the world, patent number: 201010553418.7)
3. High recovery (suitable for heap leaching, pool leaching, stirring leaching, etc.)
4. Good stability (adding effective stabilizers to reduce the interference of S, As and other harmful substances)
5. Widely used (used in gold oxide ore, primary ore, sulfuric acid slag, gold concentrate, anode mud, etc.)
6. Easy to use (PH value 10-12, dosage usage can be completely in accordance with cyanide method)
1) The dosage of cicada can refer to the dosage of sodium cyanide, and it is suggested that the beneficiation test be carried out and the optimum conditions be taken into account; (The concentration of cicada is generally kept at 0.3-0.8 in the gold oxidized ores of about 1-2 g/t, and adjusted appropriately according to different ore grade and harmful components);
2) Calculating method of dosage: the dosage of Jincicada tonic= (optimum concentration Value-measured concentration value) *water quantity of dosing pool; assuming that the optimum concentration value of Jincicada is 1.5 (according to water quantity), the concentration of Jincicada in backwater is 0.6, and 500 square water in poor pool, the dosage of Jincicada tonic is (1.5-0.6) *500=450 kg.
2) Carbon pulp technology (stirring leaching): crushing, grinding, carbon leaching, analytical electrowinning, smelting;
1. Scope of application of gold leaching agent / metal dressing agent:
(1) Suitable ore types: gold, silver oxide ore, primary ore, high-sulfur and high-arsenic gold ore, cyanide tailings, gold concentrate, sulfuric acid slag, anode mud, etc.
(2) Applicable benefication processes: heap leaching, pool leaching, carbon slurry (stirring leaching), etc.
2. Product form of cicada: solid block or granular;
3. Dissolution method of golden cicada: It can be used after water is fully dissolved at room temperature (usually in flowing water or after full stirring will accelerate the dissolution; when heaping, a dosing tank can be built at the edge of the lean liquid pool, so that the returned water after charring can directly wash golden cicada into the lean liquid pool);
4. Regulation of alkalinity: Lime or caustic soda is generally used to regulate and maintain pH value of 10-12; when the pH value of backwater decreases, alkali should be adjusted in time; when the pH value is too high for a long time (more than 12), alkali scales can easily affect the adsorption of activated carbon, or liquid passivation can affect the leaching effect.
