Selectivity and power of frothers in copper ore flotation

Selectivity and power of frothers in copper ore flotation 517 The ore was crushed in a jaw crusher to obtain particles smaller than 1 mm in size. Prior to each flotation experiment, the crushed material was wet ground in a steel ball mill. The size distribution of the ore, used as the flotation feed, is presented in Table 1. Table 1.

The frother strengthens the surface tension of the air that is injected into the flotation cell. As the air rises in the shape of bubbles, they come into contact with the mineral laden collector which

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

Froth Flotation Metallurgist & Mineral Processing Engineer

Lime is often used in flotation to increase the alkalinity of the pulp. An alkaline pH increases the volume of the froth (possibly increasing the rate at which mineral is recovered), and depresses pyrite. Frothers such as pine oil and Dowfroth 250 are used to create a froth capable of

Froth Flotation Process Detailed Explanation With

Apr 06, 2020· The most commonly used frothers are generally the compounds of carbonyl group, hydroxyl group, amino group and a carboxyl group. Alcohol-based frothers are the best type of frother. Frothers can be divided into two parts. 1. Natural frothers examples Pine Oil, Cresol etc. 2.

Methyl Isobutyl CarbInol

MiBc is used as a frother in the flotation process. MiBc absorbs at the water-air interface, aids in the production of bubbles, and stabilizes the flotation froths. Two major types of frothers in commercial use today are short chain aliphatic alcohols and polyglycols. MiBc is the most commonly used alcohol frother due to its many advantages:

TESTING FLOTATION FROTHERS

Since flotation frothers are used to reduce bubble size and increase froth stability, in the procedures adopted in this paper they were characterized by their ability to reduce bubble size in a flotation cell and to increase foam stability. It has been shown that the developed frother classification

Frothers impact surface tension, loading capability and mass removal rate, all of which influence flotation performance. As a result, choosing the proper frother can have significant impacts on recovery, selectivity, and productivity as well as environmental footprint. The use of FrothPro™ 507 improved copper recovery

Flotation collectors Solvay

AEROPHINE®, AERO® and AEROFLOAT® collectors (promoters) are used extensively for the flotation of sulfide minerals including copper, gold, lead, zinc, nickel, iron and many others, such as lithium. These products provide improved performance and higher selectivity than more traditional sulfide collectors and better overall metallurgical

Commercial copper production was declared on March 1, 2009, when copper concentrate inventory levels surpassed the 5,000 tonne shipping threshold. Increased zinc levels in the ore body, as it was continuously being mined, prompted the construction of a Cu/Zn separation circuit as extension of the previous flotation circuit.

Copper-Molybdenum ores Danafloat

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
