Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.

The increasing complexity of ore deposits, declining ore grades and higher global demand for copper has resulted in increased ore processing by flotation plants around the world.

This table lists the Orica Mining Chemicals specialty flotation collectors that are most suitable as 1 for 1 replacements for xanthate, depending on the ore type and the most predominant minerals present. The reagents detailed below offer similar performance at an equivalent or lower dosage.

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.

Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is

COPPER MINING. Open pit mining is generally employed with trucks or train haulage of ore to the nearby concentrator. However, there are a few underground mines using block caving methods. CRUSHING COPPER ORE

This study is focused on the froth flotation reprocessing of a copper mineral from flotation tailings. The effects of flotation parameters including pulp density, collector dosage, frother dosage, and dispersant dosage were statistically examined to obtain an effective approach for concentrating copper minerals.

What is Copper Flotation? Copper flotation is a process in mining used to separate copper minerals from the ore. This helps get pure copper from the ground. how copper flotation works, why it is important, and its benefits.

In this section, we carry out a case study to maximize the ore grade in the copper concentrate and determine the best operating conditions (for example, reagent dosages) of the flotation process in a mineral processing plant in Chile.
