Economic Potential for reprocessing Copper Mine Tailings in Chile. Malte Drobe, Axel Schippers, J#252;rgen Vasters BGR Hannover, Germany,, . Abstract Four copper mine tailings in Chile were investigated for their elemental and mineral composition, in order to evaluate the potential for economic reprocessing.

Tailings will not be extracted at the margins of the deposit, at the interface of the tailings with the original ground surface level, safety barriers at the dam walls and the tailings left insitu for internal water barriers. A total of 46 million tonnes at a grade of % Cu is not currently in MVCs mine plans.
We plan to construct a copper concentrator at the tailings resource which can supply both concentrate to the Sable Refinery while selling excess concentrate into the market. We are well positioned to take advantage of the expected increasing need for copper as the worlds demand for cleaner energy such as electric vehicle rapidly expands.
If developed, the mine would be the largest in the Philippines and among the largest copper mines in the world. The proposed mine site covers an area of approximately 10,000 hectares. If approved, the mine was estimated to yield an average of 375,000 t/y of copper and 360,000 ounces per annum of gold in concentrate over the 17 year period of mining and ore production.
Shouxin Tailings copper mine project Report summary Minera Shouxin Peru plans to develop the Shouxin iron ore tailings project, treating Shougang''s Cu and Zn tailings in a /a capacity plant with an initial life of 20 years.

#0183;#32;Folldal Verk A/S opened the Ulveryggen copper mine in 1972, and operated its flotationbased ore dressing plant next to Repparfjorden until closure in 1978. During those years, million tonnes averaging % Cu grade was extracted ( Nussir, 2017 ) and approximately 1 million m 3 of mine tailings were deposited in the fjord ( Christensen et al., 2011 ).
On August 4, 2014, a copper/gold open pit mine at Mount Polley, British Columbia had its huge tailings pond dam (an earthen dam) suddenly burst, massively polluting downstream streams, rivers and lakes (and probably eventually the Pacific Ocean at the mouth of the Fraser River, not to mention underground aquifers which had already been polluted during the years before the catastrophe.
Tailings is a common byproduct of the mineral recovery process. In hard rock mining, the rock containing the ore is pulverized in a series of crushing and grinding processes in order to extract the mineral. This process is also known as comminution,, grinding the ore into fine particles.
#0183;#32;Los Andes Copper has received results from the ongoing prefeasibility metallurgical study on its Vizcachitas copper project which, consistent with all prior test work conducted, confirms the adoption of dry stacked tailings at the Chile asset. During 2020, Los Andes has continued metallurgical testing at the SGS laboratory in Santiago, Chile.
Mine Closure and Restoration Plan The closure and restoration plan should cover reclamation of tailings deposits, waste rock deposits, any open pit areas, sedimentation basins, and abandoned mine, mill, and camp sites. Mine reclamation plans should incorporate the following: Return of the land to conditions capable of
