ORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS K.G

A well known aspect of ore deposit expression is the association of particular ore types with particular host rock assemblages, i.e., the orehost rock association (e.g., Stanton, 1972). This association broadly reflects the geological environment and processes that have formed the ore.

The intrusions ran into a variety of host country rock and subsequent shrinking from cooling as well as other events; have fractured and brecciated the country rocks and even the intrusions themselves. These fractures, pores and other openings left ample avenues for hot hydrothermal fluids to move into the primary ore body.

The ore was formed by supergene enrichment of host BIF with both structural and mineralogical controls on ore distribution. Age of ore formation is put at 1800�1650 Ma. In 1915 the first major iron ore mine in Australia was opened at a massive hematite deposit at Iron Knob by BHP Pty Ltd.

Secondary ores, called oxide ores, formed as weather and other natural forces altered ancient rocks. Both types of ore are mined and processed to extract the copper. Primary ore minerals of copper include malachite, azurite, chalcocite, bornite, and cuprite. One of the more familiar and beautiful minor ore minerals of copper is chrysocolla.

In the late 18 th and early 19 th centuries, the primary demand for copper was for sheathing the bottoms of boats, to protect against shipworm and seaweed. Copperbottomed vessels were both faster and required less docking time than their untreated counterparts. The Royal Navys decision to rehull their entire fleet in the 1780s gave Britain a strategic advantage during the Napoleonic Wars

Jun 06, 2012· Although the host rocks to the Lumwana copper sulphide mineralization have been correlated with the Lower Roan by previous authors (Benham et al. 1976; McGregor 1965), the observation of progressive alteration from hanging wall gneiss to ore schist suggests that this is untenable. Further consideration of the whole rock data also suggests a

Innovations Introduction to Copper Mining  Extraction

Innovations Introduction to Copper Mining Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Oxide Ore. The copperbearing solution is collected and pumped to the extraction plant where it is purified. It progresses through a number of steps that combine an organic solvent or sulfuric acid to the solution until the copper concentration is high enough for effective electroplating. Tailings are made up of very fine host rock (i.e
