Between sources, the performance of slag cement is relatively similar due to the nature of the process of iron production. Fly ash, on the other hand is the result of the combustion of pulverized coal and coal chemistry has a wide range of chemistry from source to source. The combustion process can also vary greatly from source to source.
Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.

Slag and Ash As discussed in the Background, solid waste from conventional pulverized coal-fired power plants is a significant environmental issue due to the large quantities produced, chiefly of coal fly ash, and the potential for leaching of toxic substances e.g. heavy metals such as lead and arsenic into the soil and groundwater at disposal sites, and accidental releases from coal ash ponds.
Apr 13, 2011 Continue to heat the slag until you can observe the molten gold begin to dissolve away from the rest of the slag. This occurs because of the melting point and the density of the gold as compared with the different melting points and densities of the other metal components of the slag. The gold should slip down into the smelting vessel.
