BIF-hosted iron mineral system A reviewScienceDirect
Unlike many other metal systems such as orogenic gold porphyry copper or MVT lead and zinc the BIF-hosted iron system contains several significant ore types defined by various proportions of oxides and hydroxide mineral species and with characteristic contaminants (e.g. P Si Al) and physical properties (e.g. hard-consistent friable-inconsistent blue dust).

Gold Extraction Recovery Processes911 Metallurgist
During comminution there is a generation of abraded iron surfaces from grinding media and the broken particles can be deposited on gold surface changing gold particles characteristics and its behavior during recovery processes such as flotation and leaching. In this way gold particles are smeared and its natural properties are affected.

2.4 Iron oxide copper-gold mineral system Geoscience
Iron oxide copper-gold (IOCG) deposits (Hitzman et al. 1992) are a diverse family of mineral deposits characterised by the following features (1) Cu with or without Au as economic metals (2) hydrothermal ore styles and strong structural controls (3) abundant magnetite and/or hematite (4) Fe oxides with Fe/Ti greater than those in most igneous rocks and (5) no clear spatial associations

Gold processingGold processingMining and concentrating The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g. 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

Gold The precious metal Gold information and pictures
Gold is the most malleable and ductile metal which makes it very easy to work with.It never tarnishes and is unaffected by most chemicals. However it can discolor by exposure to chlorine bleach and certain detergents. Pure Gold lacks resistance to pressure and easily bends.
