Flotation Collector Dosage – Collection of Froth
What happens when there is too much flotation collector, how do you know and how can to estimate? The bubble will react as if there is too little depressant. Froth bubbles will get smaller and closer together, but the unlike the depressant it won’t cause the mineral to fall off of the bubble due to overloading. […]
Flotation Depressants
First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s […]
Chemical Reaction of Copper Minerals and Cyanide
In discussing the Reaction Products from Copper Minerals and Cyanide you will find that when an excess of copper mineral is acted upon by cyanide solution, dissolution of copper continues at a decreasing rate until equilibrium is established and no more copper goes into solution. The rate will vary with the particular mineral used as […]
Cyanide Concentration and pH to Depress Sulphides
The chart displays how the Cyanide Concentration (how much NaCN) is needed to effectively Depress Sulphides like Pyrite, Sphalerite, Chalcopyrite but not Galena at various pH. It is pH that affects/impact the required effective concentration of cyanide. The higher the pH, the less NaCN is needed as CaO/Lime also acts as a Sulphide depressant. The use of […]
The Importance of pH in Flotation
In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline […]
Controlling Flotation Reagents
A flotation operator has two areas of control over his circuit, physical, and chemical. By physical controls I mean things such as the density, grind and the pulp levels of the cells. The chemical controls are normally only the amount of reagent flow, the type of reagent, and the point oe addition. To verify the operator’s […]
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 […]
