方铅矿、闪锌矿和一定量的黄铜矿、黄铁矿和毒砂存在不影响浸取率。

The existence of galena, sphalerite, certain amount of chalcopyrite and arsenopyrite does not influence the leaching rate.

金矿的主要载金矿物分别为：毒砂、磁黄铁矿、黄铁矿、方铅矿和闪锌矿。

The main gold bearing minerals include arsenopyrite, pyrrhotine, pyrite, galena and sphalerite.

试验表明巯基乙酸对黄铁矿、方铅矿和黄铜矿有抑制作用，对毒砂和闪锌矿没有抑制作用。

Test results show that galena, pyrite and chalcopyrite can be depressed well by TGA, but sphalerite and arsenopyrite can not be depressed.
