The company announced its intentions for a silver gold tailings project in Sonora, Mexico where it has access to materials accumulated from production at the El Tigre mine between 1903 and 1938.
In order to maintain the normal mining operations, several methods are proposed for tailing disposal, including disposal of dry or thickened tailings in impoundments or free standing piles, backfilling underground mine workings, subaqueous disposal, and the most common method, the disposal of tailings slurry in impoundments that involves the transport of tailing mass in slurry pipes to an impoundment and thereafter consolidation under their own weight and compaction to form a tailing dam.

engineering design of tailings dams in other mining industry sectors, for both stability and environmental performance. For instance, experience gained with leach pad liners is being transferred to linings for tailings ponds, and the use of synthetic lining materials is growing .
1 The combination of hydro cyclone and the vibration sieve: the tailing will go through hydro cyclone first,and then the under flow will go to high frequency vibration sieve for dehydration, which can make the tailing water content within 16%, the over flow of the hydro clone usually by thickener machine and filter press for dehydration. 2 Directly use of thickener, filter filter: the front investment is larger for this method, and applicable scope is smaller, sometimes can39;t satisfy the ...

In dry stacking, a company reduces water content of the tailings to around 15%, and dumps them onto a liner. Then the mining company compacts the tailings in the hopes of inhibiting rainwater and snow melt from soaking in and re hydrating the tailings.
