2023.3.3 Copper slag, a waste solid produced in the copper smelting process, is a high-quality secondary resource with huge output. The recycling and utilization of copper slag is of great interest because it avoids the loss of valuable metals and the threat of harmful metals, and saves a lot of natural resources and energy. This paper firstly

2017.6.16 Country: Children, boys and adults work daily, weather permitting, digging rocks out of the slag heaps adjacent to the non-operating lead mine at Kabwe. The larger rocks are piled, crushed by small hammers, bagged, and ultimately sold as building material. The rocks contain up to 5 percent lead and are highly toxic.

The charge, using a borax cover, for obtaining the most basic slag was: Ore, 0.5; PbO, 1; NaHCO3, 1.5 A-T.; and KNO3, 12 g. This was found to be the most basic flux that could be run even approximately satisfactorily. A very slow and long fusion was required.
