Agglomeration of fine-sized copper ore in heap leaching

Dec 01, 2020 The fine-sized copper ore was first mixed with metakaolin in a plastic case before agglomeration. After this first mixing, the ore–metakaolin mixture and alkali activator solution were mixed in a plastic case by rapidly hand spraying the latter over the former, and the resultant mixture was subsequently transferred to a polyethylene cylindrical drum (11.2 cm in diameter and 13.3 cm in length

Agglomeration technique improves heap leaching process

Jul 05, 2018 Ore fines, leachate and binder are continuously fed into the rotating drum at predetermined rates to promote optimal agglomeration. The binder causes the fines to become tacky, picking up other fines as they tumble in the drum. Combined with the rolling action, this creates an effect similar to that of rolling a snowball.

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

Tailings are made up of very fine host rock (i.e., gangue) and nonmetallic minerals separated from the values during beneficiation. The physical and chemical nature of tailings varies according to the ore characteristics and the beneficiation techniques used. Tailings are a slurry of fine-grained rock material and process water.

Copper Mining and Production Processes Explained

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper.

Agglomeration Drums in the Heap Leaching Process

Heap leaching, a process by which metals such as gold and copper are recovered from ore, has long been a method of choice in ore beneficiation, with applications growing all the time.. While this process has proven to be efficient, often chosen for its cost-effectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum.

Processing of Nickel Laterite Ores on the Rise

In the agglomeration stage, ore fines are fed into an agglomerator (aka ore drum), where they are tumbled with the leachate solution to cause the ore fines to be more uniform in shape and size, allowing the leachate to more effectively percolate through the heap and jump-start the leaching process.

Garpenberg (Fig. 17) is considered the most productive zinc underground mine in the world. In 2017, the mine output was 2.63 Mta of ore, with lead, copper, gold and silver being produced in addition to zinc. The Tara Mine in Ireland is Europe‘s largest zinc mine. The ore is extracted there from a depth of about 1000 m (Fig. 18).

1.3 Flotation and subsequent processes (refractory ore processing) The flotation process is described in detail in chapter 3.3. Native gold, gold tellurides, and sulphides that contain finely disseminated gold can be floated and recovered in a concentrate. In gold metallurgy flotation is often used as a pre-enrichment process for refractory ores.

Iron processing Ores Britannica

Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is
