Chromite Ore an overview ScienceDirect Topics

The chromium content ranges from 34 to 42 that of silicon from 38 to 45 and that of carbon from 0.05 to 0.06. The mix order is similar to that of smelting high-carbon ferrochromium except that it requires a source for additional silicon. It is produced by smelting together chromite ore and quartz.

Antimony Minerals Education Coalition

Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite antimony sulfide and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite tetrahedrite and ullmannite. It is mined in China Bolivia South Africa and Mexico.
