采用木炭做燃料,每产一吨粗銅(原矿品位5％左右)要用40多吨木炭,相当于砍伐460立方木炭。为了早出銅,多出銅,支援国家建设,許多森林已大量砍伐,造成損失。要避免(或減少)这种損失,利用儲量丰富,分布面广的白煤煉銅不但燃料費用可以比用焦发降低60—70％,更主要的是能解决冶金工业遍地开花,快速发展的燃料供应問題,又保护了森林,因此不但具有經济意义,还具有政治意义。我們試驗白煤煉铜,煉出粗銅兩百多公斤,質量尚好,而且燃料只为一般的50～70％。每煉一吨粗銅(矿石品位5％)需白煤15吨左右,比用焦炭量只高 The use of charcoal as fuel, each producing one tonne of crude copper (about 5% ore grade) to use more than 40 tons of charcoal, equivalent to cutting 460 cubic charcoal. In order to get out of copper early, more copper, support national construction, many forests have been cut a lot, resulting in losses. To avoid (or reduce) this loss, the use of rich reserves, widely distributed white coal copper not only fuel costs can be reduced by 60-70% compared with coke, the more important is to solve the metallurgical industry everywhere, the rapid development of fuel Supply issues, but also protect the forest, so not only economic significance, but also political significance. We test white coal copper refining more than 200 kilograms blister copper, the quality is still good, and the fuel is only 50-70% of the general. Each refining one tonne of crude copper (ore grade 5%) need about 15 tons of white coal, only higher than the amount of coke
