An efficient approach for lead extraction from waste funnel glass through the lead smelting process has been proposed. To clarify the effect of funnel glass addition on the degradation of magnesia-chromite refractories by ZnO-containing fayalite slag the corrosion behavior of magnesia-chromite refractories in lead smelting slags with different funnel glass additions from 0wt to 40wt was tested.

Carbon Refractories in an Oxidizing Process Copper
Oxidizing processes such as copper concentrate smelting traditionally use magnesia and/or alumina/silica refractory materials. The main objection to the use of carbon‐based refractories as the exposed working lining in oxidizing applications is the potential for free oxygen to react with the carbon at high temperature which could rapidly

Copper processingRoasting smelting and converting
This oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining. At this point the copper is cast into anodes the shape and weight of which are dictated by the particular electrolytic refinery.
