In the ore form, zinc compounds include sulfides, silicates, carbonates and oxides. Franklinite is a zinc oxide that also contains oxides of iron and manganese. Zinc sulfide, known as zinc blende, provides more than 95 percent of the metal ore. Zinc has uses in several industries.
Zinc metal is produced using extractive metallurgy. The ore is finely ground, then put through froth flotation to separate minerals from gangue (on the property of hydrophobicity), to get a zinc sulfide ore concentrate consisting of about 50% zinc, 32% sulfur, 13% iron, and 5% SiO 2.
Most gold comes from South Africa, making up almost half of the world’s resources, but can also be found in the United States, Australia, Brazil and Russia. Silver can be found in other ore deposits, like lead, zinc, gold and copper.
Ore is first mined, then put through a series of processes to refine and purify the copper. The USA is the second largest producer of copper in the world. The USA is the second largest producer of copper …
Where Does Silver Come From Silver is mined from under the earth surface just as gold is. While most metals come from an ore (gold comes from gold ore, copper from copper ore) silver is usually mined from gold ore or from copper, lead or zinc ore. Small amounts of silver are mined from silver ore but this equates to only about 25% in total.

Zinc is mined from several different minerals, including sphalerite (zinc sulfide), smithsonite (zinc carbonate), hemimorphite (zinc silicate) and zincite (zinc oxide). Other zinc-bearing minerals include willemite and hydrozincite. Zinc ore is mined in Canada, Australia, the USA, China, Peru.
The ore goes through various stages of comminution, followed by froth flotation, where metal concentrates are collected. Copper and lead concentrates are sent to smelters for the production of crude metals. Zinc concentrates are roasted and the silver-rich calcine residue is sent to a lead smelter for further processing.
