炭浆法提金工艺中存在着跑炭失金问题，本文研究了原矿和尾矿的碳含量变化，并由此直接得出操作回路中的炭耗。测得结果表明，在正常炭浆法生产中，炭耗值往往超过１００ｇ／ｔ指标，而达到１２０～２１０ｇ／ｔ，这部分碳仅占矿浆量的万分之几，又磨的较细，其中近半粒度小于３２５目，人们不易觉察，但随碎炭流失金的数量却相当可观．
Coking gold extraction process there is the problem of running away from carbon loss of carbon, this paper studies the carbon content of the ore and tailings, and thus direct operation of the loop to draw the carbon consumption. The measured results show that in the normal production of carbon slurry, the carbon consumption is often more than 100g / t index, and reached 120 ~ 210g / t, this part of the carbon slurry accounts for only a few very few, but also mill fine, which Nearly half the grain size is less than 325 mesh, people are not easy to detect, but the amount of gold loss with the charcoal is considerable.
