Leaching metals particularly iron there's also bases metals and sulphur on the volcanic. Metal concentration in the hydrothermal fluids, volcanic and recycled seawater, are really low- just fractions of a percent. So how do we end up with the ore that makes up 20- 30% metal? The next slide will be on the seafloor to explain this.

Diamond is a solid form of pure carbon with its atoms arranged in a crystal. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common allotropes of pure carbon are diamond and graphite.In graphite the bonds are sp 2 orbital hybrids and the atoms form in planes, with each bound to three nearest neighbors 120 …

This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore. As such, certain steel smelters in China have developed a process for blending nickel limonite ore with conventional iron ore to produce stainless steel feed products.

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.

A truckload of specular hematite gravity concentrate was obtained from the Ozark Ore Co., Iron Mountain, Mo. This particular lot of ore contained, in percent: Fe 55.3, SiO2 9.3, Al2O3 3.5, CaO 4.8, MgO 0.60, P 0.007, and S 0.009. Portions of this material were arc-furnace-smelted in experiments that paralleled those on low-grade ore.
