HELSINKI, 27Dec /EuropaWire/ The technology group W228;rtsil228; will deliver a turnkey power plant to provide electricity for the Phase Two expansion of the Tasiast mine located in Mauritania. The contract has been signed with Tasiast Mauritanie Ltd, a subsidiary of Kinross Gold Corporation, the Canadabased gold mining company.
Large trackmounted drills prepare the ore for blasting, and the broken ore is hauled to the oredressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 metres (3,300 feet) below the surface, and tunnels are extended to the ore body.

THE CHEMISTRY OF THE EXTRACTION OF GOLD Cu(CN); and Cu(CN). The insoluble gold cyanide compound AuCN precipitates from acidic solutions of aurocyanide ions as follows Au(CN); + H+ = AuCN + HCN. (15.2) This reaction takes place readily in strongly acidic solution and slowly in weak acid solutions (pH 2 to 3).
The Phase Two Tasiast expansion will bring the African mines average annual production to 634 000 oz for the tenyear life of the project,
The secondphase expansion at Tasiast will push mill capacity up to 30,000 tonnes of ore per day to produce an average of approximately 812,000 gold ounces annually for the first five years, Kinross said.
Plant construction is now 93% complete. Initial low grade Phase W ore is expected to be encountered in mid2019. Tasiast Phase One project development is progressing well, and continues to be on time and on budget, with full commercial production expected by the end of June. Plant construction is now 93% complete and the remaining

The mineral dressing is the processing of removing gangues from ore which is a technique to extract purity by extracting mineral element, andit is the essential and absolute process. After this process, it can be sent to a smelting factory with reducing freight costs and it volume.
Key facilities in the plant were ore storage and handling, milling and classification, preleach thickening, leaching, adsorption, residue disposal, gravity concentration, electrowinning and smelting, and reagents storage and handling.
Detailed study results for a combined Phase One and Phase Two 30,000 t/d expansion can be found in an updated NI 43101 Technical Report for Tasiast available on the Company website at ..kinross. The Phase One feasibility study has been reviewed by thirdparty independent reviewers and was found to be consistent with

Mining in the Upper Harz region of central Germany was a major industry for several centuries, especially for the production of silver, lead, copper, and, latterly, zinc as well. Great wealth was accumulated from the mining of silver from the 16th to the 19th centuries, as well as from important technical inventions.
