Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).
What do you recommend as a pH probe to measure pH in cyclone overflow tubs and in flotation cells. I have used Foxboro's but they drift within 2-3 days and once this drift occurs the measurement of high pH (>11) becomes problematic and have to be re-calibrated frequently. The pH probes are not alw

Flotation processes are based on the different surface wettability properties of materials (Wang et al., 2015).In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium
FLOTATION Flotation is the most widely used mineral separation method. It is the preferred method of mineral recovery for many of the most important minerals that are recovered and large tonnages of ore are processed by flotation annually. The underlying principles of the flotation process are well established but it has proved to be

Hello recently, I am working on processing of a gold bearing mixed oxide-sulfide copper ore (Av. Cu; 0.80 & Av. Au; 0.2ppm). After some research and testing different methods, I found Controlled Potential Sulphidisation (CPS) Flotation as the most effective & practical method on similar ores
A calibrated probe, designed especially to measure cavitating acoustic fields (Gaete et al., 1993), has been used to determine the effective intensity of the acoustic field present in the flotation cell. The probe’s design was based on stainless steel and brass, which transforms external mechanical disturbances into electrical signals that

12.1 COPPER ORES AND MINERALS. More than 170 copper-containing minerals are known and only 10-15 of these minerals have any economic value. The most important economic copper minerals are chalcopy-rite, chalcocite, bornite and covellite. Table 12.1 lists the copper minerals of economic value.
Copper ores are typically concentrated by either froth flotation or hydrometallurgical extraction, both of which have unique process challenges. Froth flotation is wrought with measurement difficulties; surfactants will coat measurement elements and report incorrect results where xanthates will continuously attack probe bodies and measurement

Flotation process are widely used for copper extraction. The ore pulp slurry is pumped to flotation cells for extracting. The flotation cells are divided into several parts: roughing, concentration and scavenging (the exact numbers of stages for each part should be decided by test work to reach the best recovery), and with the use of frothing
Jul 06, 2017· With copper ionization, acidic water will increase the risk of copper staining on the pool lining and surfaces. So, there is an added importance to testing pH on a regular basis. However, the ionization process is pH neutral, so you should not have as much fluctuation in pH as you would with a salt chlorinated or traditional chlorine pool. Also
A typical copper operation contains many floatation cells, often with a pH sensor in each cell. The number of sensors and their locations vary from plant to plant, being largely dependent on solution chemistry. Sensor life and maintenance quickly becomes important economic factors.
