How Mill Tonnage Affects Flotation and its Reagent Dosage
The first item on our list that an operator will be concerned with is the TONNAGE. There is a misconception common amongst operators to the effect that when reagents are added to the ore being processed, you are treating the mineral, or the amount of mineral that is in the ore. That is not correct. […]
How to be a Flotation Operator – Job Description
The problem that most flotation operators have in learning their job (after reading the Job Description) isn’t with the flow sheet or the mechanical equipment. It is how to recognize the effects that the variables have on each other. The main operating tool that any operator has to use is their own five senses and a […]
Flotation Modifiers – Activators – Depressants
This branch of chemicals will prepare the mineral surface so other reagents will be able to collect the metal. For Conditioners and Modifiers, it may be simply cleaning the surface of the particles, as in the case of removing oxidization, or it may be a chemical that these are the chemicals that bind the mineral […]

Flotation Collector Manufacturers
There are several Flotation Collector Manufacturers, but may half-a-dozen really good ones. What makes a quality may Flotation Collector supplier is the dependability and consistency of the product. Yes price matters but trusting what you buy it worth a few pennies extra. Now would you select as a Flotation Collector Manufacturer depends on what you need. If you need […]
Flotation Collectors
Simply said; a Flotation Collectors is a chemical used to make the surface of minerals, which is metallic, hydrophobic or in layman’s term ‘afraid of water’ or ‘water hating’ as others like to say. This chemical used will behaved, in a way, as a wax would when you applied it to your car. After wax (or […]
Work Index and Sample Size
In mineral processing, is the Bond work index of an ore different if the determination is made at a finer grind size? Is rock hardness is independent of testing size? The answer to this question is that generally no, the size that the index is measured at does not effect the Bond work index value. Bond work […]

Lead Depression in Bulk Cu/Pb Flotation
A series of tests were completed with bulk copper and lead flotation with the depression of lead and flotation of copper. This alternative utilized MBS as the primary depressant in both the bulk and reverse circuits. The challenge of this scheme is that the lead concentrate will be the tailings of the reverse circuit and will likely […]
Clay Depressant
A Clay Depressant commonly used in South Africa to help produce a cleaner froth flotation concentrate is: Product: Oxfloat 108 Preparation: Make 1% solution in water. Add product to water into stirred beaker to prevent lumping. Allow sufficient time to dissolve. Dosage: Dosage varies widely depending on Clay content and ore characteristics. 30 – 150 g/t.
