摘要
本文叙述了金矿样品焙烧的意义,指出焙烧是个复杂的反应过程。研究了焙烧温度、升温速度、矿物组合及分段焙烧。提出了二氧化锰为新的助燃剂。它不仅有效地促进了有机物及硫化物的分解,而且可节省分解样品用的大量氧化剂。
The baking is of importance for gold ore samples. The authors put em-hasis on the complex process in the baking process, and suggest the manganese dioxide to be a new combustion assistant,through which, not only the decomposition of organic matters and sulphide can be promoted effectively, but also the great amount of oxidant can be sa ed which are used to decompose specimen The baking temperatuire, rate of temperature rising, make-up of ores and baking in phases are studied.
