Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

This The evaluation of a copper flotation plant performance by plant survey and laboratory tests 101 indicated that it is possible to increase the Cu grades by cleaning easily. Therefore the recovery must be as high as possible. Consequently, the laboratory tests and plant scale studies showed that it is possible to obtain a concentrate with ...

1. Introduction. In porphyry/skarn copper–gold flotation plants gold recovery is often well below copper recovery [1].With liberated and copper-associated gold readily recovered in the flotation stage, this recovery difference is often due in part to operating strategies that require rejection of gold-bearing iron sulphide gangue minerals in order to …

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 three product solution illustrated above can be somewhat simplified by taking an intermediate tailings sample between the two stages of concentration; i.e., a copper tail (zinc feed) sample in the previous example. Then, adding the notations: Copper tail (zinc feed) = CT with copper and zinc assays = c 5 and z5. Assume mill feed, F, as …

Fig. 2 shows the P 80 of different mineral species in an ore for a major copper operation. These values vary significantly, with the P 80 of total solids, sulfide minerals, iron minerals, copper minerals and molybdenum are ∼ 200, 105, 125, 94 and 85, respectively.

flotation models are linked. For example, a laboratory test conducted on a drill core sample, intended to represent a portion of the orebody, is conducted at a specific grind (represented by a P 80). However, when that ore is actually processed through the plant it may well be (and in many cases most likely will be) at another P 80 ...

The intercept is zero, because the adjustment led to the regression line passing through the zero value. It must be borne in mind that, although we study a specific flotation process for copper ores, its oxidized degree can vary within a range. Therefore, the range of copper grades in the feed was also chosen as independent variables for its …
