Concentrated acids with the requisite high degree of purity are available commercially, but they can be purified further by subboiling distillation [42]. Detailed discussion of the properties and applications of these reagents may be found elsewhere [20, 22-25].

lead ore

Most ores contain less than 10% lead. Ores are crushed and concentrated by froth flotation typically to 70% or more. Sulfide ores are roasted, producing primarily lead oxide and a mixture of sulfates and silicates of lead and other metals contained in the ore. Lead oxide from the roasting process is reduced in a coke-fired blast furnace.

Lead, zinc and copper smelters each having different smelting practices either give a low return, no payment or a penalty for metals adverse to the particular process. For instance, copper contained in a lead concentrate is paid for at or near the price paid for lead while lead in a copper concentrate will return less than 50% of lead price.

PROPERTIES OF LEAD

Besides this lead is slow to corrode and there are many examples of lead articles which have lasted for centuries. Lead is relatively abundant. Lead concentrates can be easily extracted from the ore and winning the metal from the concentrate does not need much energy. This reflects also in a fairly low price compared with other non-ferrous metals.
