The paper presents the results of laboratory studies on the flotation of coppermolybdenum ore from the Kazakhstani deposit using a combined reagent. A combination of butyl xanthate, a noninogenic collecting agent with a thioamide group – TC100 thionocarbamate and higher aerofloat (Reafloat series) was used as a combined flotation reagent.

2. 2. Flotation Procedure All the flotation testwork was done using the Denver laboratory machine with a stainless steel flotation cell. The required mass of nickelcopper 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

Flotation Reagents Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to .
minor amounts of copper. Laboratory scale milling and flotation testing of ore samples taken from this operation was performed. Different grinding media and conditions were used, including ceramic, stainless steel and steel. Flotation tests used a sequential recovery protocol for selective flotation of first the lead and thereafter the zinc. The
· Modifiers may activate poorly floating minerals such as sphalerite, or may depress certain minerals, so that a differential flotation can be performed on a complex ore. Chemicals that change the pH of the slurry are also used as modifiers. pH modifiers include lime, soda ash, sulfuric acid; can act as activators and/or depressants by controlling the alkalinity and acidity of the slurry.

In the paper, the flotation of a porphyry copper ore in the NovaCell is described. The head grade was % Cu, and the copper mineral was freed from encapsulation at a relatively coarse size. The initial grind size was 600µm. Tests were conducted in a laboratory unit, in both batch and continuous modes, using a conventional reagent suite.
In the iron ore mining fraternity, in order to achieve the desired quality in the froth flotation processing plant, stakeholders rely on conventional laboratory test technique which usually takes more than two hours to ascertain the two variables of interest.
