根据我厂进厂铜精矿品位每生产一吨电铜要产出六吨左右弃渣,按当前产量逐年增加,估计年产出弃渣高达15～18万吨。我们认为电炉弃渣研磨成矿砂渣代替从远地运来的优质建筑河砂用于工程建筑符合变废为宝的环境保护方针。在文化大革命及批林批孔运动的推动下,我厂与昆明市修缮公司混凝土预制厂等部门一起,全面作了矿渣砂混凝土强度、力学性能、矿渣砂浆,矿渣混凝土构件试验。熔渣水
According to our factory into the plant copper concentrate grade every ton of copper produced to produce about six tons of waste residue, according to the current output increased year by year, it is estimated that the annual output of up to 150,000 to 180,000 tons of waste slag. We believe that electric furnace slag grinding ore dressing slag instead of high-quality construction river sand shipped from far away for the construction of buildings in line with the environmental protection guidelines turning waste into treasure. Under the impetus of the Cultural Revolution and the Pilot Hole Campaign, the factory made a comprehensive test on the strength, mechanical properties, slag mortar and slag concrete components of slag sand concrete together with the concrete prefabrication plant of Kunming Repair Company. Slag water
