lead ore smelting in pakistan
Primary lead is mined, separated from ore, and refined into various products, whereas secondary lead is recovered from used objects – such as used lead-acid batteries – for reuse in other products. Smelting is a key process in lead product production, and involves heating lead ore or recovered lead with chemical reducing agents.
12.6 Primary Lead Smelting 12.6.1 General15 Lead is found naturally as a sulfide ore containing small amounts of copper, iron, zinc, precious metals, and other trace elements. The lead in this ore, typically after being concentrated at or near the mine (see Section 12.18), is processed into metallurgical lead at 4 facilities in the U. S.

Lead smelting and lead alloy classification; Lead mining; Lead metal can be classified as either primary or secondary. Primary lead is produced directly from mined lead ore whereas secondary lead is produced from scrap lead products (such as automobile batteries) which have been recycled.
Another advantage derived from the adoption of high-lime slags when smelting ore containing arsenic is the production of less speiss (a by product heavier than matte, resulting from careless operation of the furnace, in the lead being driven out of the crucible and sows built up).
LEAD INDUSTRY PROFILE LEAD PRODUCTION About 60% of lead produced world-wide is derived from ore. Lead ore is mined in many countries around the world, though three quarters of world output comes from only six countries: China, Australia, USA, Peru, Canada and Mexico. Small amounts are mined in several countries in Europe, with the biggest producer

Ancient smelting was done using loads of lead ore and charcoal in outdoor hearths and furnaces. Although lead is a common metal, its discovery had relatively little impact in the ancient world. It is too soft to be used for weapons (except possibly as sling projectiles) or for structural elements.
Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.
