Introduction . Froth flotation is defined as a physico-chemical process which exploits the differences in the electrochemical
Obtaining high recovery in copper flotation plants has been always under investigation in recent years. Misreported copper into tailing dramatically declines copper recovery. This study aims to find the possible reasons of copper loss to tailing and present the methods to improve the performance of the Sarcheshmeh copper plant flotation …
Additionally, the flotation plant residence time will often be determined solely by the grinding circuit capacity and feed slurry density. In the case of SAG mill – ball mill circuits, the fluctuations in ... that would be determined for a typical copper porphyry material. A typical set of pulp kinetic parameters derived from an MFT
2. 2. Flotation Procedure All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about

This data on chemicals, and mixtures of chemicals, commonly known as reagents, is presented for the purpose of acquainting those interested in froth flotation with some of the more common reagents and their various uses.. Flotation as a concentration process has been extensively used for a number of years. However, little is known of it …
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 ...
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 …
The feed to a copper flotation plant is 150t/h, with a feed grade of 2.5%. The filtered concentrate after 24hrs is 255 dry tonnes. Given that the grade of the material lost as tailings is 0.12% and the metal recovery was 88%. Determine how much material in tonnes is lost as tailings. Calculate the concentrate grade. Calculate the % metal loss.

Without have access to the complete metallurgical testwork data and results I'd say 2.5X was the extra chosen to factor in Moly recovery which The Book calls for 2.6X.
Some copper flotation plants are equipped in such a manner as to allow them to treat oxide minerals either separately or in conjunction with sulfide minerals depending on the relative abundance of oxide copper in the feed. It is usually also apparent that the proportion of oxide copper making up the plant feed is very important. This ...
