Lead-zinc ore refers to natural mineral formations containing lead and zinc metals, typically in sulfide forms such as galena (PbS) for lead and sphalerite (ZnS) for zinc. Lead-zinc ore mining involves the extraction and processing of lead and zinc ores...

Chromite ore is a mineral that contains chromium, a metal used primarily in the production of stainless steel and other alloys. Chromite ore is a critical raw material in the production of stainless steel and other alloys, making it an...

Iron ore is a mineral substance which, when heated in the presence of a reductant, yields metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore in...

Copper ore refers to natural rock formations that contain copper minerals in concentrations high enough to make extraction economically viable. Copper ore typically occurs in two main types: sulfide ores and oxide ores. Oxide Ores: Oxide ores contain copper oxide...

Placer gold refers to gold that has been eroded from its source (such as gold-bearing quartz veins) by natural processes like water, and then concentrated in deposits known as placer deposits. Prospectors historically panned for placer gold by swirling sediment...
