过去,我厂用过的镀金底座清洗液是送外单位回收黄金,回收成本高,效果差。后来,我厂电镀组利用电镀工艺原理,自己回收黄金,收到了显著效果。回收的办法是在镀金底座清洗过渡槽里挂上正负二块极板,极板材料为不锈钢,面积为16.5厘米×25.5厘米,加上10伏电压,通以5安培电流。通电后,清洗液里的金离子将不断沉积到负极板上,从而可以在负极板上不断回收黄金。 镀金底座清洗液的成份与电镀液相同,即为
In the past, I used the gold-plated base cleaning fluid is sent to the unit recovery of gold, high recovery costs, poor results. Later, I electroplating plant plating process using the principle of their own recovery of gold, received a significant effect. Recycling method is to hang the positive and negative plates in the plating tank cleaning transition groove, the plate material is stainless steel, an area of 16.5 cm × 25.5 cm, plus 10 volts, through 5 amperes. After the power is turned on, the gold ions in the cleaning solution will be continuously deposited on the negative plate, so that gold can be continuously recovered on the negative plate. Gilded base cleaning fluid composition and the same plating solution, that is
