The mining reagent is an aqueous solution of dialkyl dithiophosphate. It has little frothing properties. The main application is the flotation of zinc sulphides, e.g. sphalerite and marmatite, where the selectivity of the product towards pyrite is advantageous. Another application is flotation of copper sulphides. In both cases, for optimum recovery a scavenger collector is often needed. It can be added undiluted or preferably diluted with clear water to 5-20% solutions. It is good practice to stir before use.
Its dosage varies with the type of ore, usually falling within the range of 10-100 grams per metric ton ore.
The product is effective in the pH range of 4 to 12

It is biodegradable. The majority of the collector is tied up with the concentrate and is destroyed in the subsequent processing operations. The remainder is transferred to the tailings . Release into the water systems should be avoided.
