gold flotation concentrate的意思|示意

This article mainly describes testing results, process design and production aspects of bacterial oxidation extraction for a kind of arsenic flotation gold concentrate.

主要介绍某含砷浮选金精矿细菌氧化提金工艺的试验研究成果，工艺流程设计及生产情况。

The average leaching recovery of gold reaches 86.01% from high grade raw ore and flotation concentrate of gold in pilot test.

半工业试验对浮选金精矿和高品位原矿平均金浸出率达86．01％。

Ther new technique is especially fit to treat flotation gold concentrate. The emulsified liquid membrane must be oil water (oil wrapped water) and contain flowing carrier.

新技术特别适合处理浮选金精矿，所用的乳化液膜应该是油包水型、且含流动载体的液膜。

However, when the technology of bacterial pre-oxidation and cyanide leaching for flotation concentrate of gold is used, the leaching rate of 92.73% is reached.

对浮选金精矿采用细菌预氧化—氰化浸出工艺，金浸出率可达到92.73%。

It showed from experiments that the best approach to the treatment of fine grained disseminated gold ore was hot press oxidation of flotation concentrate of pyrite followed by cyanide leaching.

试验结果表明：对含金黄铁矿精矿进行压热氧化—氰化浸出，是处理该微细粒浸染型金矿石较有效的方法。
