摘　　要：湖南某金矿尾矿金品位偏高很多,通过在现有药剂制度的基础上添加黄原酸酯作为强化捕收剂进行浮选试验,使得尾矿金品位由原来的1.05 g/t降到0.75 g/t。通过对尾矿库中的尾矿进行尼尔森选矿试验,使得金的品位由1.20降到0.8 g/t。For a gold ore of Hunan, by means of adding xanthic esters to the original reagent system as intensive collecting reagents, the grade of the tailing produced during the proeessing deereases from 1.05 to 0.75 g/t. The grade of the tailing from the tailing pond would decrease from 1.20 to 0.80g/t after a Nelson concentration process.
