RENASA produces liquid and aqueous ditiophosphates, the difference between them being that one group carries cresyilic acid and the other, a certain alcohol in their molecule. These reagents are mostly used to float silver-bearing sulfides, as well as some other kinds of minerals in alkaline circuits.
All dithiophosphates are employed in aqueous solutions, in concentrations previously assessed in the laboratory, with exception of Ditiophosphates AR – 125 and AR - 131, which are insoluble in water.

A rapid action collector, used in the silver / lead flotation circuits, especially in single flotation cells. It performs very well in neutral and alkaline circuits, with good synergy in the Xanthates. |
Preferred collector in the recovery of silver/lead due to its selectivity degree. |
The is the most selective of the three, usually in those circuits that require recovering the greatest amount of silver; another unique property of this reagent is that it can also be used in zinc flotation circuits. |
This is a collector that is used in copper, lead and silver flotation circuits, where zinc selectivity is required. |
A collector with good synergy when acting with Sodium Isopropyl Xanthate, to reduce consumption and to obtain a better recovery of the valuable minerals, such as marmatite and esphalerite. |
Collector used in the flotation of copper - silver sulphurs, due to its selectivity to sulphur. It is also used in the Scavenger circuits, improving the recovery of the values that are lost in the tails. |
This collector performs well in slightly acid circuits with pH values between 6 and 7. In combination with the AR-1242 it forms a synergetic mixture that produces better results in the recovery of copper, lead and zinc. |
A collector of excellent synergy with the xanthates, when used as a secondary collector in the recovery of lead, silver, copper and gold. |
High selectivity collector due to its short carbonate chain. It is employed in any flotation circuit using finely milled material. |
Collector developed based on Sodium Amyl Dithiophosphate. This reagent is used pure on copper – molybdenum circuits; one of its greatest virtues being its lower consumption as compared to Sodium Isopropyl Xanthate and to AP-3302.
In addition, it obtains good copper recoveries and is a good molybdenum collector, being very selective opposite to the pyrite. |
The unique property of this collector is use in zinc flotation in replacement of Sodium Isopropyl Xanthate, its main characteristic being its selectivity opposite to the pyrite.
This reagent is a secondary collector that helps to obtain better grades and recoveries. |
This secondary collector was especially designed for sulfured lead - silver minerals, its outstanding property being its excellent selectivity opposite iron and zinc in a bulk flotation circuit. |
