Pinto Valley has been in operation since 1972 and has produced more than four billion pounds of copper since then. Capstone acquired it from BHP in October 2013. The operation consists of an open-pit mine, a 60,000 tonnes per day ("tpd") concentrator plant and a 25,000 tpd SX-EW plant.

INTRODUCTION This paper presents a "case history" of the steps taken to estimate capital and operating costs for a typical porphyry copper concentrator of ±9,070 metric tons (10,000 short tons) per day capacity.

This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.

 — The high grade concentrate is thickened and filtered in the high grade oxide copper thickeners at the concentrator plant prior to transfer to the leach plant for electrowinning of copper in the leach plant high grade circuit.

 — The US$2,460mn copper concentrator plant in Chile has a throughput of 95,000tpd, producing copper concentrate and molybdenum concentrate. BHP has extended the line of mine at Spence in Chile by 50 years after …

Objectives: This study aimed to optimize the bioleaching condition of two indigenous iron- and sulfur-oxidizing bacteria from the Meydouk mine, Iran, and evaluate their function in a semi-pilot ...

 — BHP CEO Mike Henry led the opening of Spence's new copper concentrator plant today. The project required an investment of US$2.46 billion and has a throughput of 95,000 tpd to produce copper concentrate and molybdenum concentrate.

 — KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO, 11 OCTOBER 2021 – The ramp-up of Kamoa Copper's Phase 1, 3.8 million-tonne-per-annum (Mtpa) concentrator plant continues to advance ahead of schedule, with approximately 320 000 tonnes of ore milled in September.

 — We support custom copper processing plant, flow design. JXSC is equipped with advanced equipment and high-quality mineral processing plant, high recovery concentrate rate, so as to achieve a win-win goal for customers.

Copper concentrates are typically processed via pyrometallurgy-hydrometallurgy consisting of smelting, converting, fire-refining and electro-refining (Fig. 4 and Table 6).
