The predominantly angular shape and hard cutting edges of copper slag allow for fast cleaning action and hence, excellent for surface profile preparation. Copper slag from the production plant at PMBA is produced from the highest quality raw copper slag sourced only from Japan, and is not mixed with any recycled or tin slag. PMBA produces ...
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 …
