Where is cassiterite mined in the world?

Where is cassiterite most commonly found?

Most sources of cassiterite today are found in alluvial or placer deposits containing the resistant weathered grains. The best sources of primary cassiterite are found in the tin mines of Bolivia, where it is found in hydrothermal veins. Rwanda has a nascent cassiterite mining industry.

Why is cassiterite mined?

The hardness of cassiterite enables it to survive stream transport, and its high specific gravity causes it to concentrate in deposits that are large enough and rich enough for mining. Other high-specific-gravity minerals might also occur in these deposits, improving the economy of mining.

Where is cassiterite found in Australia?

Carbonate-replacement deposits (such as found in western Tasmania, e.g., Renison) form some of the largest tin deposits in Australia. Cassiterite (SnO2) is by far the most important tin ore in all deposits. Small amounts of tin are also recovered from sulphide minerals such as stannite (Cu2FeSnS4).

Where is cassiterite found in Uganda?

Cassiterite is found in SW Uganda in hydrothermal and pegmatite veins (often associated with columbite-tantalite) although detrital and eluvial deposits also occur.

How do you mine cassiterite?

The alluvium is broken up by a high pressure jet of water and the resulting slurry is pumped to the concentrating plant. The cassiterite rich slurry is further concentrated by gravity separation methods, which involve flushing the slurry with a stream of water over equipment such as jigs, spirals, or shaking tables.

How is cassiterite formed?

The cassiterite is formed by hydrothermal process and occurs as veins, alluvial, and placer. The grains are resistant to weathering.

Is Uganda a South African?

Uganda is located in eastern Africa, west of Kenya, south of South Sudan, east of the Democratic Republic of the Congo, and north of Rwanda and Tanzania. It is in the heart of the Great Lakes region, and is surrounded by three of them, Lake Edward, Lake Albert, and Lake Victoria.

Where is gold mined in Uganda?

Precious metals including Gold are also found in Kigezi, Buhweju, Mubende, Busia, Namayingo, Bugiri, and Karamoja.

How is cassiterite used?

Cassiterite contains 78.6% Sn and are the principle tin ore throughout ancient history and remains the primary source of tin metal, used as plates, cans, containers, solders, and polishing compounds and alloys.

What is cassiterite used for in phones?

Tin (produced from cassiterite) – used inside your cell phone and all electronic products as a solder on circuit boards. The biggest use of tin worldwide is in electronic products. … Tantalum (produced from “coltan”) – used to store electricity in capacitors in iPods, digital cameras, and cell phones.
