temperature, a dry, insoluble, solid slag is formed. When slag makes contact with the refractory lining of a furnace wall (or other areas of the holding vessel) that is colder than the melting point of the slag, the slag is cooled below its freezing point and adheres to the refractory lining. This adhering material is called buildup.

Gold melts forming a ingot and in the top i have the slag. A bit of gold is in that slag, because there is a decrease and matter is not created or destroyed so i save the slag of all funditions i do. when i have enought i crush them, and now i have a lot of slag crushed with a bit of gold that i want to recover.

What is the current environmental performance of the Trail smelter?

Historically, at least two smelters discharged slag to the river, including the Trail smelter. Slag is a granulated by-product of the smelting process that does not present a human health risk. It is a glass-like compound consisting primarily of silica, calcium, and iron, which contains small amounts of base metals including zinc, lead, copper ...

Slag

This glassy appearance is caused by the formation of slag on the ore's surface during the smelting process. Slag consists of the undesired impurities in the metal ore extracted during the smelting process. However, it also protects the liquid metal undergoing the smelting process by providing an oxide layer (crust) on the smelted metal.
