Different Types of Iron Ore - Mineral Processing & Metallurgy

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Calculation of Ore Tonnage & Grade from Drill hole Samples

MINERAL ORE RESERVE Case 1. When all holes have positive values, let a, b and c, be the depth of ore in the three holes forming the prism; to find the average depth of the ore influenced by any given hole, use the formula: d = 4a + b + c/6. Then, as one proceeds from hole to hole, b and c should be substituted, thus: 4b + a + c/6 and 4c + a + b/6,
