mohs hardness mangan ore

Mohs hardness will scratch or abrade a material with a lower number. Calcium carbonate is a soft mineral with a Mohs of 3. Since ground calcium carbonate is a naturally mined material, impurities exist in all ore bodies. Almost all contain some dolomite (CaMg(CO 3) 2) with a Mohs of 4, while others contain mica (Mohs 3) or graphite (Mohs 1-2).

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.

Monazite is a reddish-brown phosphate mineral that contains rare-earth elements.Due to variability in composition, monazite is considered a group of minerals.
