According to the International Lead and Zinc Study Group, global refined Pb production in 2019 decreased by 0.3% to 11.76 Mt, and metal consumption decreased by 0.5% to 11.81 Mt, resulting in a production to consumption deficit of about 50,000 tons of refined Pb due to the decline in automobile production and increased uses of Li-ion batteries.
After driving across so much of the Ozarks' Springfield Plateau a couple of weeks ago, I thought I'd make a return visit to Joplin to visit their mineral museum in the city park on the west edge of town. The museum tells the story of lead and zinc mining that caused the community in southwestern Missouri to grow into a boomtown in the last years of the 19th century.

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.
Effects of lead and zinc on plant growth. The quantification of biomass produced after 45 days of treatment indicates that all four metals used in the study decreased the growth of S. carnosa plants, even at low concentrations. Among the metals, zinc had the least impact on plant growth, followed by nickel, copper, and finally lead, which appeared to be the most harmful.
The lead and zinc ore resources are mostly found in Yunnan, Inner Mongolia, Gansu, Guangdong, Hunan, and Guangxi, and their reserves account for over 70% of the national total reserves. The lead and zinc ore resources in China encompass more lean ore than rich ore, and their structure and mineral composition are quite complex. The average grade ...
Currently, in Angola, 36 of the 51 minerals considered the most critical in the world are known, some of which are about to go into production. The list will be revised, if necessary, every five years, in consultation with mining …

Zinc (Zn) is a bluish-white lustrous metal that is brittle at room temperature, but malleable when heated. It has a low melting point (419.5°C) and a moderately high specific gravity (7.13). Lead (Pb) is a soft, ductile, malleable, bluish-white metal with a low melting point (327.4°C) and a high specific gravity (11.3). Zinc and lead minerals often occur together because, as elements, they ...

The gold and silver dissolve more easily in zinc than in lead, and when the bullion is cooled slightly, zinc dross rises to the top, bringing the other metals with it. Extraction of lead ore from the underground surface is achieved by the method of rock drilling. This is done using the heavy-duty machinery of blasting with dynamites.
