Copper–gold ore processing with ion exchange and SART technology
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 copper–gold ores: A dithiophosphate collector at an alkaline pH must be used (controlled by lime or soda ash if the pyrite content in the ore is low).

Copper–gold ore processing with ion exchange and SART
The industrial validated technology used in gold mining that deals with copper‑gold ores is the SART process, which allows a viable treatment for these complex The processing characteristics of copper–gold ores vary from ore to ore and are closely related to the mineralogical composition of the ore. Based on composition, the ores can be classified into porphyry copper–gold ores containing pyrite, porphyry copper–gold ores with negligible pyrite content, and altered supergene copper–gold ores.Flotation of Gold and Gold-Bearing Ores ScienceDirect

Hydrometallurgical Processing ScienceDirect
Thus, hydrometallurgy is the study of water and metals. Most metal production includes some hydrometallurgical processing to obtain a finished metal product. Many metals can be produced by hydrometallurgical processing from minerals. Some metals, such as copper and gold can be processed from crushed ore to purified metal 3. Iron oxide copper gold ore Properties of iron oxide copper gold ore Iron oxide copper gold ore refers to the symbiosis of copper ore and gold ore in gold ore in some form. Its amount is about 10 million to 4 billion tons. IOCG ore contains copper with a grade of 0.2% to 5% and gold with a content of 0.1 to 1.41 grams per ton.8 Types of Gold Ore Properties and Ways to Process

Cyanidation of a copper-gold ore ScienceDirect
The ongoing depletion of gold and silver-containing ore deposits demands a shift towards the processing of more complex sources. Leaching of gold or silver from these sources, which are named refractory and are typically low-grade, can be complicated due to one or more of the following effects: (1) kinetic or thermodynamic impediments on Section snippets Materials. The sample of copper-rich pyritic refractory gold ore which was obtained from copper-rich zones of the Mastra deposit (Gümüşhane/Turkey), was crushed to −4 mm and then ground for 30 min to −73 μm (P 80) by using a laboratory rod mill.The ground ore was riffled and then fed to a rotary sample divider (Fritsch Recovery of Au and Ag from the roasted calcine of a copper

Treatment of copper-rich gold ore by cyanide leaching,
Copper cyanide complexes in cyanide leach solutions deteriorate the recoveries of gold. Herein, five phosphonate-based [P204] − ionic liquids were synthesized, which were pioneered to apply to extraction of copper cyanide complex ions in cyanide leach solutions. In the extraction process, macroscopic layered solids rich in copper cyanide The global decrease in ore mineral grades and increase in ore mineralogical complexity has triggered the modern mining industry and research communities to search for efficient methods of processing ores which were initially considered uneconomic [1, 2].Gold-bearing copper minerals are common occurrences in Overview of the Challenges and Opportunities in Processing Complex Gold

Mabilo Copper-Gold Project Mining Technology
Mabilo copper-gold project development phases. The Mabilo copper-gold project is proposed to be developed in two stages, with the first stage involving direct shipping ore (DSO) of near-surface oxide portion. The second stage includes the development of a 1.35Mtpa purpose-built facility to process initial ore.As expected, the copper in the circuit reduced to a low level, but when sulfide copper–gold ore processing resumed, the copper concentration in the leach circuit did not attain previous levels even though a higher copper orebody was being mined.

Highlights of the Past Five Decades of Gold Ore
Gold mineralogy plays an important role in gold ore processing and Canadian mineralogists and metallurgists made great contributions to it in the past 50 years. The developments in gold mineralogical study in Canada can be divided into three main eras: 1960s 1970s, 1980s 1990s and 2000s. In the 1960s and 1970s, gold mineralogy This paper presents an ore-sorting algorithm based on image processing and machine learning that is able to classify rocks from a gold and silver mine based on their grade. The algorithm is composed of four main stages: (1) image segmentation and partition, (2) color and texture feature extraction, (3) sub-image classification using neuralPerformance evaluation of optical sorting in mineral processing
