某硫精矿中含铁42.3%、有效硫47.34%、金0.72 g/t,对其进行了焙烧—氰化浸金试验研究。其结果表明：在750℃下焙烧2 h,获得含铁61.42%、金品位1.04 g/t的焙砂；在硝酸铅添加量为300 g/t条件下,对该焙砂进行氰化浸金时,浸渣金品位可降低至0.33 g/t,金浸出率可达68.27%。

Roasting-cyanidation gold leaching process is carried out toward a sulfur concentrate with iron grade of 42. 3%,effective sulfur 47. 34% and gold 0. 72 g/t. The result is that:roasting with the temperature of 750℃ for two hours obtains calcine with 61 . 42 % iron and 1 . 04 g/t gold; The gold grade of cyanide slag can be reduced to 0. 33 g/t and gold leaching rate can reach 68. 27 %,when the cyanide leaching of gold from the calcine with 300 g/t lead nitrate added.
