What Is The Difference Between Rock Mineral Ore And Metal
Or a mineral or an aggregate of minerals from which a valuable constituent especially a metal can be profitably mined or extracted is an ore Metal An alloy of two or more metallic elements Therefore Rocks have minerals which in large concentration are called ores and these are mined for metals.

Why another book about Ore Deposits There are a number of factors which motivated us to write this text and which may provide an answer to this question Firstly our colleagues are predominantly mining engineers and minerals processing technologists which provides us with a different.
Origins Of Hydrothermal Ores Science
1 Mineral compositions both isotopic and elemental provide several clues The isotopes of 15 elements often identify the source rocks their ages and the time of mineralization Thermodynamic stability and measured or calculated solubility of the mineral assemblages limit the processes contributing components to the ore solution the chemistry of transport and the conditions and causes.
