Slag is a liquid on Serpulo manufactured by melting Scrap in a Melter. It is an intermediate liquid for processing Scrap into other materials, but it can also be used in the Wave and Tsunami to fire damaging melting projectiles. Puddles that form from Slag emptying from an exposed Conduit or from liquid-based turrets will cause explosions and large fires when touching Oil, as well as ...

Smelter slag is obtained in the process of metallurgical converting of copper concentrate in the Smelter Plant in Bor, Serbia. Today, the reserves of this material are evaluated at about more of a year, with the average copper content of 0.6-0.9%. Production of copper concentrate by flotation of smelter slag has started in 2001.

Increased demand of copper in the last few decades resulted in the generation of a large amount of smelter slag. About 80% of the world's copper to date was produced from sulfide ores by concentrating followed by the pyrometallurgical operations such as smelting and refining (Heimlich et al., 2010, Fan et al., 2014).While slag from blast furnace in iron making has found …

To maintain slag quality, good housekeeping is essential at all stages. General rubbish must be kept from entering the slag pits, and the bunds or walls enclosing the pits, which may be simply a ridge of aggregate, should be made of the same material in case some is recovered with the cooling slag during excavation.
