The proposed collectors can be used at any flow rate, which provides the extraction of the desired metal, lycous useful particles of ore, preferably 5-10 - 2510 kg / kg of ORE.
Foaming agents must be used for froth flotation. Any kind of known foaming agent is suitable, which leads to the extraction of good Gnogo metal ore useful particles.
Example 1. Penn flotation copper sulphide.
15,500 g of copper ore, chalcopyrite copper sulphide ore, pre-packaged, is placed in a rod mill with 257 g of deionized water. Copper ore contains 80.2% of a particle size of 75 microns or less. A certain amount of lime is also added to the rod mill, based on the desired pH value for subsequent flotation. The rod bar is then rotated at a speed of
60 rev / min, a total of 360 revolutions. The crushed suspension is transferred into a cell of 1500 MP of a flotation machine, stirred at a speed of 1,150 rpm
30 and the pH value is adjusted to 10.5 by adding an additional amount of lime, if necessary.
The collector is added to the flotation cell (in the amount of 50 g / t), and then conditioned for 1 minute, during which the DOV FROTH foaming agent (in the amount of 40 g / t) is added. After additional conditioning for
e0 1 min. air is fed into the flotation cell at a rate of 4.5 l / min and automatic vanes are started to remove the foam. Foam samples are taken at time 0.5; 1.5; 3; five
ds and 8 min, dried overnight in an oven with flotation tails. The dried samples are weighed, divided into suitable samples for analysis, ground to ensure a suitable fine grain size.

and dissolved in acid for analysis. Samples are analyzed using a plasma spectrograph.
The results show that the proposed compounds are effective in extracting the copper sulfide mineral and exhibit a significant degree of extraction and selectivity of the mineral.
Example 2. Copper oxide ore from the Central African Africa (CUjO) is subjected to froth flotation in example 1, using 1 t of AO g of frother Dowfroth l Removing the Copper Mineral fossil age by 14.8% relative to the known) collector.
Example 3. Sulfide ore from Central Canada, containing copper sulfide, nickel sulfide, platinum, palladium and gold, is subjected to a Series of frothy flotation described in Example 1 using the proposed collectors and several well-known collectors. A Sowfroth 1263 foaming agent is used at a concentration of 0.00625 pounds / ton (3.12 g / ton). Collectors use at a concentration of 0.0625 pounds / ton (31.2 g / t). The foam obtained is removed at time points 0.5; 1.0; 2.0; 4.0; 7.0; 11.0 and 16.0 minutes A comparison of the results shows the possibility of reducing pyrrhotite recovery to 15.5%. A significant improvement also manifests itself in reducing the loss of platinum, palladium and gold.
Example 4. Penn flotation copper sulphide.
500 g of copper ore from Western Canada (high grade chalcopyrite copper sulphide ore with a small amount of pyrite) together with 257 g of deionized water are placed in a rod mill having 1 inch rods, and the mixture is ground for 420 revolutions at a speed of 60 rpm, to get the particle distribution 25% below 100 mesh. A certain amount of lime is also added to the rod mill based on the desired pH for subsequent flotation. The crushed suspension is transferred to a 1500-mb cell of a flotation machine. The flotation cell is stirred at a speed of 1150 rpm and the pH value is adjusted to 8.5 by adding an additional amount of lime.
The collector is added to the flotation cell in an amount of 8 g / t, after which it is conditioned for 1 minute, at this point Dowfroth 250 foaming agent is added in an amount of 18 g / ton. After additional conditioning, air is fed into the flotation cell at a rate of 4.5 liters / min for an additional 1 minute and automatic vanes are turned on to remove the foam. Foam samples are taken at time 0.5; 1.5; 3; 5 and 8 min.
