AQUARIUS brand environmentally friendly gold extractant

　　AQUARIUS brand environmentally friendly gold extractant is a new type of environmentally friendly and low toxicity product developed and produced by our company,which has passed ISO9001 international quality system certification.It can completely replace the highly toxic sodium cyanide.This product is low toxic and environmentally friendly,suitable for heap leaching,pool leaching,and carbon slurry production of oxidized gold ore and low sulfur primary gold ore.

　　When adsorbing gold from precious liquid,activated carbon has a better adsorption effect.Zinc wire can also be used as a substitute,or resin can be used for adsorption.The leaching effect of gold is better when the ambient temperature is above 15℃.And it can be compatible with the sodium cyanide leaching process and mixed for use.

　　Product form:Grey powdery solid/granule

　　Packaging and specifications:25kg±0.1/bag(620*380*120mm)

　　Main ingredients:Sodium oxide,iron,sulfur,ammonium ions,chloride ions,etc

　　Scope of application:Suitable for heap leaching,pool leaching,and agitation leaching carbon slurry processes in gold mines

　　Product advantages

　　1.Low toxicity and environmental protection

　　The product has been tested and identified by the"Liming Chemical Research Institute"and is non flammable,non explosive,has no oxidant hazard,no radiation hazard,and low toxicity.Belonging to ordinary chemical products,environmentally friendly and safe.

　　2.High leaching efficiency

　　Strong chelating ability,capable of effectively leaching gold and silver from ores,with high leaching rate.

　　3.Fast leaching speed

　　The leaching cycle is shorter than using sodium cyanide(which can shorten the leaching time by 15-30%),and the recovery is faster.

　　4.Strong anti-interference ability

　　The product has stable performance and strong anti-interference ability.The presence of small amounts of harmful substances such as arsenic As and sulfur S in the ore does not affect the leaching effect.

　　5.Easy to use

　　The product is easily soluble in water and the usage method is basically the same as that of sodium cyanide,making it easy to prepare and use.

　　6.Strong adaptability

　　Adapt to the production of heap leaching,pool leaching,and carbon slurry processes for gold mines of various scales.

　　Instructions for use:

　　Dosage of medication:100-1500 grams per ton of ore.

　　Heap spraying process:Prepare a solution with a mass concentration of 0.03-0.1%using clean water for spraying;

　　Stirring leaching process:It can be configured as a 10%-15%solution for addition,or directly added to the stirring tank in solid form.The concentration of reagents in the leaching slurry is generally between 0.03-0.1%.

　　1.Firstly,use lime or other alkali to adjust the alkalinity of the ore heap or slurry,and adjust the pH value to 10-12.

　　2.During heap leaching or pool leaching,prepare a certain concentration of gold extractant solution for spraying or soaking based on the optimal leaching concentration determined by the experiment.

　　3.When stirring and leaching,leaching should be carried out according to the optimal slurry concentration,gold leaching agent concentration,leaching time and other conditions determined by the experiment.

　　4.During the leaching process,the concentration of the leaching agent should be regularly measured.When the concentration decreases,the leaching agent should be added in a timely manner.

　　5.Due to the different composition and acidity of the ore,the optimal concentration of the reagent should be determined based on the actual amount of ore and the experimental results of the ore sample,and the leaching agent should be added in proportion.The concentration of the immersion agent can be detected according to the method provided by our company.

　　Product transportation and warehousing
