Here's some information, but there is good detailed information at the links below.

Magnetite has many uses, is one of the most common oxide minerals and also one of the most common iron minerals. It is an important ore of iron and is found in igneous, metamorphic and sedimentary rocks. It can also be abundant in sediments.

Chromite is the only ore of chromium, a metal used to induce hardness, toughness and chemical resistance in steel. The alloy produced is known as "stainless steel". When alloyed with iron and nickel it produces a alloy known as "nichrome" which is resitant to high temperatures and used to make heating units, ovens and other appliances. Thin coatings of chromium alloys are used as platings on auto parts, appliances and other products and given the name "chrome plated".

Sphalerite uses include: primary ore of zinc, mined because it contains minor amounts of indium, cadmium, germanium or gallium.

It looks like there's a fourth mineral, but your main title question rolls off, and I can't read it. It starts with a "c." I've tried about three different ways to read it, but I guess it's just too long. Have to ask another question to get that one. Sorry about that.
