General processing technologies for copper ore are summarized as below: II.
Apr 24, 2017· This was the first commercial method used for gold extraction. Place the ore into the mortar and grind it to the size of sand grains. Put the ore grains into a plastic bowl. Add the 35-percent hydrochloric acid to the sodium hypochlorite bleach into a flask or beaker, in a two-to-one ratio of acid to bleach. Ensure that the liquid mixture is at ...
Gold in iron oxide copper–gold deposits - ScienceDirect. 1. Introduction. Since the discovery of the supergiant Olympic Dam deposit in Australia in 1975, Iron Oxide Copper–Gold (IOCG) deposits have become the largest producer of uranium (Hitzman and Valenta, 2005, Skirrow, 2011), the third producer of copper (Sillitoe, 2012) and significant producer of gold (Kerrich et al., 2000 ...

May 22, 2018· You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin.

Jul 14, 2013· Copper minerals are found in many different ore deposit types and settings, including porphyry, iron oxide-copper-gold (IOCG), volcanogenic massive sulphide (VMS), strataform and strata-bound deposits. Copper porphyry deposits are by far the most common copper ore type, however they tend to be of relatively low grade. The enormous Chuquicamata ...
Jan 01, 2016· Iron oxide copper–gold (IOCG) deposits contain economic or anomalous gold, and the gold distribution is important both for its economic significance and ore genesis. However, the gold distribution in IOCG deposits and its controlling factors remain unclear. The gold grades and tonnages of selected thirty-six deposits in some well-defined IOCG ...
Nov 28, 2018· Iron oxide copper gold ore deposits (IOCG), like Olympic Dam, can be tremendously large, high grade, and simple-to-process concentrations of copper, gold and uranium ores. Olympic Dam – which is aiming to produce 215,000 tonnes of copper for FY19 — is the third largest copper equivalent deposit, the largest uranium deposit, and third ...
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
May 21, 2021· The amount of iron oxide copper gold ore 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. Iron oxide copper gold ore tends to be conical on the edge of granite, or appears as long banded breccia or massive iron oxide ore in faults or shears.

Iron oxide copper-gold (IOCG) deposits are a recently recognised class of deposit, blessed with valuable by-products but faced with product quality challenges. These deposits, which account for 5% of global mined copper, possess diverse mineralogy with by …
Our heavy-duty iron ore balling drums are relied on by some of the industry's top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.
Jun 15, 2021· Iron oxide copper gold ore deposits (IOCG) — like BHP's Olympic Dam mine or more recent Oak Dam discovery — can be tremendously large, and simple-to-process concentrations of copper, gold and other economic minerals. The 2018 discovery hole at Oak Dam, 65km from Olympic Dam, included 180m grading 6% copper, 1km from surface.

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
