Syenite Used To Mining Gold

Jul 01, 2014 Syenite-hosted veins and associated gold mineralization. Gold was first reported in the Matachewan area in 1901, and the Young-Davidson and Matachewan Consolidated mines were discovered in 1916 and 1917, respectively (Lovell, 1967, Sinclair, 1982). Mineralization in the two mines is spatially continuous, and is considered to be one deposit, the Young-Davidson deposit.

Mining activities in the Witbank Coalfields also lead to surface subsidence due to mining acitivities. Here the expression of subsidence basins at the surface is depended on varying geological conditions including the lithology of the roof strata, the depth of the coalseam, the height of the coalseam and the mining method used.

In the past, mechanical classifiers were usually selected to operate in closed circuit with grinding mills. These devices require much floor space and have been essentially replaced in large plants, as well as small, by hydrocyclones. Since classification is a potential plant bottleneck, it is recommended that the cyclone feed system be provided with redundant pumps. It is relatively

The Mineral Reserves used a gold cutoff grade of 0.41 g/t. The M&I Mineral Resources and Inferred Mineral Resources for the Magino Project set out in the table above were taken from the Magino Technical Report. The Mineral Resources were estimated at a gold price of $1,300 per ounce. The Mineral Resources used a gold cutoff of 0.25 g/t.

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.

Original mining was from pegmatite bodies but current mining is from alaskite,a very coarse-grained, light-colored, feldspar-quartz-muscovite rock. The U.S. feldspar producers receive strong competition from Canadian producers of nepheline syenite. Nepheline syenite is used for many of the same purposes as feldspar. gold and silver
