Lime use in gold processing A review ScienceDirect

Copper-gold process flow sheets typically involve the combination of complex flotation circuits, combined with subsequent cyanidation leaching for gold recovery (Benson et al., 2007; Zheng et al., 2010; Medina and Anderson, 2020). In scenarios where gold is preferentially associated with pyrite, methods are required to separate copper Economic, energy and water analysis of copper ore process flow sheets which include a dry sand fluidised bed (DSFB) and heap leaching was performed for two distinctly different ore types. If the low density product from the DSFB is rejected, significant reduction in energy and water consumption can be realised.

Case study flowsheets: copper–gold concentrate treatment

The PLATSOL ® process may also offer a non-cyanide process treatment option for recovery of copper and gold from copper–gold and gold–copper concentrates. Ferron et al. (2002) reported on batch laboratory testing of a copper–gold concentrate and a refractory gold–silver concentrate under PLATSOL ® conditions.Ore processing is by conventional cyanide heap leaching, which produces a pregnant leach solution (PLS) containing 1–2 ppm of gold, together with 1000 ppm or more of copper. The PLS is treated by column ion exchange, using Dow’s gold-selective MINIX resin. Loaded resin is stripped with an acidic thiourea solution, from which gold and silverCopper–gold ore processing with ion exchange and SART

Current Status of Copper-Ore Processing: A Review

The head grade of copper in the ore is 1–2% and the oxidation state is ~60% [ 26 ]. The decision to use the combined technology for processing ores with the ultimate recovery of copper into a bulk concentrate (~90%), its low copper content (~5–6% copper), and the decrease in copper loss with tailings was taken after numerous tests.Mineral processing flowsheet design is the design of process flow from ore processing to beneficiation product output, in which raw ores and beneficiation products are design objects, and the design shall take into account of production process parameters, product quality, and economic benefits.
