In practice, maintaining the pulp pH value between 10.0 and 11.0 is crucial. The cyanide leaching rate of gold ore decreases if the pH value exceeds 12 due to excessive alkalinity or falls below 9 due to insufficient alkalinity.

 — The PLATSOL™ process also offers a noncyanide 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.

 — Following primary crushing, the ore is transported to the concentrator by an overland conveyor, 1.8m wide and 6.8km long. The concentrator circuit consists of two-train SAG and ball mills, followed by primary and scavenger flotation cells, vertical regrind mills and cleaning flotation cells to produce a copper-gold concentrate grading 32% copper …

 — 1. Introduction. This chapter describes units, circuits, and strategies used to recover gold that is either liberated or present in very high-grade gold particles, referred to as gravity-recoverable gold (GRG), as well as gold present in much lower grades in sulfidic particles, typically pyrite and arsenopyrite, that can in their own right be recovered by …

 — The total-oxidation process is particularly advantageous for copper–gold ores. Gold can be recovered by direct cyanidation of the washed autoclave solids. Silver, if present, will likely be fixed at least partly as silver jarosite in the autoclave solids. To improve silver recovery, a lime boil is recommended (2 h at 95°C with an excess of CaO).

 — As a matter of fact, a SART plant can reduce the operational cost and increase the incomes in a gold mine, although the main achievement is to make feasible the treatment of a gold-copper ore deposit.

 — The project supports BHP's intention to continue growing in Chile while strengthening its global copper portfolio. The new plant was built with more than 12 thousand workers and total investment reached US$2,460 million. BHP CEO Mike Henry led the opening of Spence's new copper concentrator plant today.

Over recent years, incremental throughput projects have been completed at the Concentrator allowing a greater volume of material to be processed in a 24-hour period. The downside to this is that the grind size of material sent to the Flotation plant has also increased leading to lower recovery levels of copper bearing mineral within the ore.

Hargraves Resources operated the gold copper mine, treating 450,000 t/y of ore containing 5.6 g/t gold and 0.4 % copper, and produced about 72,000 oz/y of gold and 1500 t/y copper using a mixture of gravity and flotation. Overall gold recovery was about 90%. The gravity circuit recovered about 50% of gold in feed and comprised one 30 inch Knelson

First ore was fed into the concentrator plant on May 20 and the start of copper concentrate production occurred on May 25, several months ahead of schedule. As of June 30, 313,000 tonnes of ore grading 4.85% copper had been conveyed to the run-of-mine (ROM) stockpile. The team currently is preparing for the final plant performance

 — It is estimated to contain 3.6 billion pounds of copper, 617,000 ounces (oz) of gold, and 21.3 million ounces (Moz) of silver. The underground project is expected to contain reserves of 23.9Mt, grading 1.59% of copper, 0.006oz/t of gold, and 0.139oz/t of silver. Mining and ore processing at Pumpkin Hollow copper project

Conventional flotation plant optimization procedures for copper and copper-gold ores have served the industry well over decades. But with the present trend in declining ore grades along with increase in metallurgical complexity, many flotation operations are experiencing significant challenges in sustaining design or operational budgeted recovery and …

The use of geometallurgical modelling is becoming common in the design of a concentrator plant and during its operational phase. Predictive modelling aims to define optimized process parameters for the concentrator plant to accommodate the variability of the ore feed characteristics. The main objective of this study is to simulate the metallurgical response …
