Copper Tailings

Water Reclamation and Tailings. The concentrated ore, now called copper concentrate, is dewatered and dried to about 10% moisture content. It is shipped by truck to the Asarco smelter in Hayden, Arizona. (The El Paso smelter is on stand-by status). Water is recovered from the tailings in another thickener.

Tailings Resolution Copper

Tailings. The mining process involves separating the copper ore from noneconomic rock. After removal of the copper, what remains is called 'tailings.' Tailings include particles of rock, water, and residual process chemicals. We will pump the slurry-like tailings via a pipeline to a designated facility for permanent storage.

HydroFloatTM Case Study: Copper Recovery from Tailings at

• Roughly 75% of copper in flotation tailings exists as unliberated fine-grained copper sulfides in gangue-mineral composite particles Figures: Vollert, L., Akerstrom, ., Seaman, ., and Kohmuench, J., 2019.

Tailings Reprocessing: Magna Copper Company's Pinto Valley

The Miami #2 tailings pile was deposited during the operation of a Miami Copper Company mine and mill. The operation used a gravity mill and later tlotation to separate copper from the ore. The tailings were deposited in six canyons adjacent to the mill using launders and spigot valves.

New approaches for extracting and recovering metals from

May 15, 2017 Mineral tailings from two copper mines were bioleached under different conditions. • Greatest copper extraction was achieved at extremely low pH, at 45 °C and under oxidative/reductive conditions.. Copper present in tailings PLS was selectively precipitated as CuS by biogenic H 2 S.. Microbial communities were dominated by Sb. thermosulfidooxidans and Acidithiobacillus spp.

The effect of potential heap construction methods on

Nov 01, 2016 The column bioleaching of copper flotation tailings by mixed cultures was carried out in three heap construction methods for 83 days. As shown in Fig. 2a, in Method A and B, the copper concentrations increased slowly, then remained stable in the late bioleaching stage. The addition of Yulong mineral in Method B resulted in a higher copper concentration than Method A and C.
