On the below Chart, selective flotation (separation) is obtained from the green line (1% mass) to the red line (4.5% mass). After >4.5% mass, you get mass pull, just mass. No selectivity, no concentration. You could float all day and yes get more mass. You could float off the whole tailings if you have enough time.

This is achieved by a combination of the design of the flotation machine (called a flotation cell) and the use of a second class of surfactants known as frothers. In a simplified sense, the role of the flotation machine is twofold: ... Figure X illustrates a study done on a copper sulfide ore to evaluate the frother performance of MIBC, DF-250 ...

The finish-ing touches were put to the new design while the machine was oper-ating in normal flotation service at the concentration plants. The use of OK-16 flotation machines by Outokumpu Oy is summarized in Table 1. At Keretti, a test run was conducted on a factory scale in the spring of 1972.
Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways. Flotation depends on ...

The working condition category is mainly determined by the ore properties. In the copper flotation industry site, the ore mainly comes from two mines. In the grinding process, the ore from a single mine or a mixture of ore from two mines is used. Therefore, there are three types of working condition categories in the copper flotation process.
The Pyrite Depression in a Copper Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyrite-copper, you need to bring the plant's pH up to the other side (right side) of the PYRITE curve. The more flotation collector you have on, the higher you will need to increase that pH for effective pyrite ...

A company separates nickel, copper, and kryptonite from ore by the floatation separation process, which has three steps: oiling, mixing, and separation. These steps must be applied for 2, 3, and 1 hour respectively to produce one unit of nickel; 2, 2, and 1 hour respectively to produce one unit of copper; and 1, 1, 3 hours ...
Flotation is both a science and an art. It brings together many complex variables. Such basic factors as knowledge of mineral structure, chemical reagents, pH of mill water, pulp density, temperature, technical skills of the operator, the dependability of the flotation machine, as well as a host of other factors which affect the flotation of ...

The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead. With this process, copper was recovered first with MBS depression of lead, zinc and pyrite. Lead was recovered after conditioning, utilizing cyanide as the base depression scheme to control sphalerite and pyrite.

This tells us that the concentrate has 9.57 times the copper concentration of the feed. 1.1.1 Grade/Recovery Curves While each of these single calculated values are useful for comparing flotation performance for different conditions, it is most useful to consider both the grade and the recovery simultaneously, using a "Grade/Recovery Curve".

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
