Abstract
The additive is a mixture of silver sulfide, lignosulfonate, lead nitrate and benzene sulfonate. It is added to gold-lixiviating cyanide solution to raise gold-lixiviating rate. Trial shows that it can raise gold-lixiviating rate by over 10%.
Description
The invention belongs to a kind of golden additive of carrying, relate to and contain the cyanidation gold-extracted additive of gold mine powder.
Take mechanical air blast drum oxygen or interpolation hydrogen peroxide to wait the dissolved oxygen that increase in solution to the cyaniding leaching of gold existing containing in the gold mine powder.Machinery air blast drum oxygen equipment is huge, is subjected to the solubility limit of solution oxygen, and energy consuming ratio is more serious, and the leaching yield of gold is low; Meetings such as adding hydrogen peroxide produce the leaching that side reaction makes the surface passivation restriction gold of gold.
What the purpose of this invention is to provide a kind of leaching yield that can improve gold contains the cyanidation gold-extracted additive of gold mine powder.
Purpose of the present invention realizes by the following technical solutions: described additive Containing Sulfur silver, sulfonated lignin, lead nitrate and phenylbenzimidazole sulfonic acid salt are formed, silver sulfide 50-100g, sulfonated lignin 0.1-0.5g, lead nitrate 1-3g, phenylbenzimidazole sulfonic acid salt 1-5g during it is formed, four thorough mixing yellowly flours.
Silver sulfide in the described additive can quicken the oxidation of sulfurous iron ore, and sulfonated lignin can increase the infiltration degree of cyaniding solution to breeze, and lead nitrate can make the goldc grains activation of passivation, the mass transfer that phenylbenzimidazole sulfonic acid salt can increase the oxygen in the gold leaching solution and quicken oxygen.
The present invention directly adds in the cyanide gold-leaching solution, can improve the leaching yield of gold, through its finished product being soaked No. two experiments of gold, than improving more than 10% with general cyaniding gold-extracting method, is a kind of more satisfactory cyanidation gold-extracted additive.
To contain golden troilite powder be example with per ton, silver sulfide (specifically can be added vitreous silver ore for one kilogram, be converted to the silver sulfide amount), sulfonated lignin 5g, lead nitrate 20g (according to the mineral composition adjustment), phenylbenzimidazole sulfonic acid salt 30g, thorough mixing joins in the cyanide gold-leaching liquid, and cyaniding leaching yield so just can improve more than 10%.
Claims (1)
1, a kind of cyanidation gold-extracted additive of gold mine powder that contains, it is characterized in that: Containing Sulfur silver, sulfonated lignin, lead nitrate and phenylbenzimidazole sulfonic acid salt in the described additive, silver sulfide 50-100g, sulfonated lignin 0.1-0.5g, lead nitrate 1-3g, phenylbenzimidazole sulfonic acid salt 1-5g during it is formed, above-claimed cpd thorough mixing yellowly flour.
