(一)試驗計划的提出: 高县的氧化矿,主要为含銅砂岩,靠下边的矿脉表面粘附有一层孔雀石。我們先后作过5次試驗,逐步改进了炉型,配料,操作等方面的問題,但是粗銅質量还得不到改善。通过矿石分析,才发現使用的矿石品位太低,从0.66～1.78%,这是根本原因,目前发现的矿点,最高含銅6.32%,但这只是一条矿脉中不到10公分厚的一薄层,大部份是在2%以下。結合实际情况,大胆設想,提出以炭作燃料,3%以上的矿石煉粗銅,3%以下,1%以上的矿石煉冰銅的試驗計
(A) Proposed experimental plan: Oxidation ore of Gao County is mainly copper-bearing sandstone, and a layer of malachite is adhered to the surface of the veins below. We have conducted 5 tests in succession and gradually improved the problems of furnace type, ingredients and operation, but the quality of blister copper has not been improved yet. By ore analysis, only to find the grade of ore used is too low, from 0.66 to 1.78%, which is the root cause of the ore deposits found at present, the maximum copper 6.32%, but this is only a vein less than 10 cm thick Thin layer, most are below 2%. Considering the actual situation, we boldly envisaged to put forward the experimental plan for refining ores of copper with more than 3% ore by using charcoal as fuel, 3% or less of ore, 1% or less of ores,
