flotation cell making copper ore lime mineral

Copper Flotation - Elmhurst University

The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime simply water and ground-up limestone to give a basic pH, pine oil yes, it comes from trees -- a by-product of paper mills to make bubbles, an alcohol to strengthen the bubbles, and a ...

pH/ORP measurement Copper flotation process

A high pH is important in copper ore processing to maximize this mineral’s flotation properties. Most copper ore slurries tend to be acidic. Plants typically add lime to the slurry in the mill or floatation circuit, increasing its alkalinity. A typical copper operation contains many flotation cells, often with a pH sensor in each cell.

Lime use and functionality in sulphide mineral flotation: A ...

Lime is the most common reagent used in sulphide minerals flotation, and its use in the flotation of the most common ore systems was reviewed in this paper. Lime plays a critical role by influencing collector adsorption on the different minerals, while also controlling dispersion of clays, pulp rheology, settling of particles in the thickeners ...

Flotation ore dressing Britannica

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. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Froth flotation - Wikipedia

Normally the setup is a two-stage system with 3,4 or 5 flotation cells in series. Principle of operation. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding a process known as comminution so that the various minerals

DE-ZINCING OF LEAD-COPPER SULPHIDE MINERALS FLOTATION

Typical lead-copper-zinc sulphide minerals were found hard to be separated selectively by froth flotation in the plant practice operation due to part of sphalerite was progressively entrapped into lead-copper bulk flotation. A series of de-zincing on lead-copper flotation tests has been conducted in the laboratory to reduce unwanted zinc content.

Froth Flotation - Metallurgist and Mineral Processing Engineer

3. Making conditions favourable for the desired mineral particles to adhere to air bubbles. 4. Forming a mineralized froth on the surface of the ore pulp. 5. Removing the froth from the flotation cell or vessel.

Modeling and Control of Lime Addition in a Flotation Process

Flotation is an important and versatile mineral processing technique that is used to separate hydrophobic materials from hydrophilic. This technique makes it pos-sible to mine complex ores that otherwise would have been regarded as uneco-nomic and non-beneficial. In this case flotation is used to separate copper from the unwanted gangue.

Copper ore flotation process line machine copper processing ...

Copper sulphide ore can be divided into: single copper ore, copper-sulphide ore, copper pyrite, copper-molybdenum ore, copper-nickel ore, copper-cobalt-bearing ore, etc. According to different mineral types, there are different technological methods. Almost all copper sulfide ores have sulfides containing iron, so in a sense, the flotation of ...

60 Centuries of Copper: The Flotation Process

In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.

A Comparative Study of Kinetics of Flotation of a Copper ...

Copper-nickel ore from INCO mines, Sudbury, Ontario, Canada was used in the experiments. The approximate ore composition was pentlandite 4-5%, chalcopyrite 4-5% and pyrrhotite 30-35%. The ore was ground in a polyurethane lined rod mill with stainless steel charge to avoid any external iron getting into the flotation system.

FLOTATION CHARACTERISTICS OF A COMPLEX COPPER ORE: A ...

flotation characteristics of a complex copper ore: a comparison between wet and dry grinding collected at 2, 4 and 8 minutes of flotation. After collection, the concentrates were filtered, dried ...

Copper-Cobalt ores - Danafloat

These are often associated with copper minerals and pyrite and pyrrhotite iron sulphides. Two different flotation separation strategies are used. Differential flotation sequence: A differential copper-cobalt flotation separation which begins with selective copper flotation by raising the slurry pH to 10 with lime and using a dithiophosphate ...

Copper Mining and Extraction Sulfide Ores

The ore from the mine contains about 2% copper. To get at the copper the first stage is crushing in huge cylindrical ball mills. Ball mills crush the ore into a fine powder. Courtesy of Rio Tinto. Stage 2: Froth flotation The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent.
