analysis and result of iron ore processing

Laboratory & ore analysis

Laboratory and ore analysis . Quality samples equal quality results. Taking better ore samples will produce better-quality results. This sounds easier said than done, especially in mining applications where often consignments of many thousands of tons of ore product needs to be represented by final composite ore sample sizes that wouldn''t fill a teaspoon.

Iron Ore – MSK

Iron ore pellets are spheres of typically 8–18 mm (0.31–0.71 in) to be used as raw material for blast furnaces. They typically contain 67%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolostone and olivine is added and Bentonite is used as binder.

Iron and Steel – Analysis

Demand for steel, which drives steel production, is a key determinant of energy demand and steel subsector CO 2 emissions. Global crude steel production increased by 5% in 2018 to reach 1 817 Mt, following 6% growth in 2017. Initial estimates suggest 3% growth in 2019. This follows a period of relatively flat demand from 2013-2016.
