某金矿石浸渣浮选精矿所需要的试验材料
试验物料为某金矿石氰化尾渣的浮选精矿，含金品位为29.78g/t，含银15.07g/t，含砷0.64%，含硫19.90%，含铁18.20%、SiO2 45.74%、Al2O3 8.78%。物料中的金为显微不可见包裹金，并以黄铁矿包裹为主。采用超细磨－氰化方法处理，在<37μm占99.5%的磨矿细度下氰化24h，金的浸出率仅有3.95%，难于浸出。所用试剂主要有：NaOH（IR），NaCN（AR），CaO（IR），活性炭（IR）。
The test material of cyanide leaching residue of a gold ore flotation concentrate required
Test material for a gold ore cyanide tailings flotation concentrate, gold grade is 29.78g/t, including silver 15.07g/t, containing arsenic 0.64%, sulfur 19.90%, iron 18.20%, SiO2 45.74%, Al2O3 8.78%. The gold in the material is not visible in the gold, and the pyrite is the main. By using the method of superfine grinding and cyanide treatment, the leaching rate of gold is only 3.95%, and the leaching rate of gold is only, which is difficult to be leached under the grinding fineness of 99.5% <37 m. The reagents used are: NaOH (IR), NaCN (AR), CaO (IR), activated carbon (IR), (activated carbon).
