    Roasting the ore The lead concentrate fresh from the filter needs to be further refined to remove the sulfur. After the concentrate is unloaded at what is called the sinter plant, it is mixed with other leadbearing materials and with sand and limestone. Then the mixture is spread on a moving grate. Air which has been heated to 2,550F (1,400C) blows through the grate. Coke is added .

    Sulfide ores are roasted, producing primarily lead oxide and a mixture of sulfates and silies of lead and other metals contained in the ore. Lead oxide from the roasting process is reduced in a cokefired blast furnace. This converts most of the lead to its metallic form. Three additional layers separate in the process and float to the top ...
