From the attrition-scrubber 16, the suspension is passed to a washer 17 wherein said suspension is washed with cold water. From the washer 17, the iron and ferro-aluminous impurities are extracted in suspension through line 18 and discarded, whereas the silica sand mud is fed, through line 19, into a conditioner tank 20 wherein the slurry is conditioned by the addition of from 0.3 to 1 kg/ton of sand of petroleum sulfonates, and a foaming polyalcohol in an amount of 0.05 to 0.2 kg/ton of sand, as well as, if necessary, a mineral acid to obtain a pH of from 1.5 to 7.0, which treatment is carried out for a period of from about 3 to 10 minutes, to thereafter send the conditioned mixture to the flotation chamber 21 wherein it is subjected to a froth flotation process by aeration and stirring, in order to remove the ferrosilicates and iron oxides, which are extracted from the flotation chamber 21 with the froth through a trough 22, whereas the silica sand which sunk into the flotation chamber. is extracted through line 23 and sent to a second conditioner tank 24, for the addition of fatty amines (preferably a mixture of primary and secondary amines) in a proportion of 0.1 to 0.5 kg/ton of sand, as well as hydrofluoric acid and sulfuric acid in an amount sufficient to activate the aluminosilicates and to obtain a pH of from 1.5 to 3.5, which conditioning takes from about 0.5 to about 1.5 minutes, and thereafter the conditioned mixture is sent to a second flotation chamber 25 wherein the aluminosilicates are entrained in the froth through trough 26, whereas the sinking purified silica sand is extracted through line 27 and conveyed by means of a suitable conveyor 28 to a suitable storage space 29 for purified silica sand.
Magnetic separation and froth flotation are common beneficiation equipment in the ore dressing process, mainly used to beneficiate the required ore.

We had an excellent third quarter financially and operationally with strong performances at all three operations driving costs significantly lower. This included another record quarter at Island Gold, and Young-Davidson starting to demonstrate its full potential following the completion of the lower mine expansion. We previously outlined our expectation to transition to strong free cash flow generation in the second half of 2020, and we delivered with record free cash flow of $76 million in the quarter, said John A. McCluskey, President and Chief Executive Officer.
Simple, cost effective magnet assembly incorporates Erium™ Ceramic or Rare Earth Tube magnets into a grate assembly to remove ferrous contamination from free flowing products as it cascades through the grate.

Silicified wood: Silicified "petrified" wood is formed when buried plant debris is infiltrated with mineral-bearing waters which precipitate quartz. This quartz infills the cavities within the wood and often replaces the woody tissues. This specimen is about four inches (ten centimeters) across and is from Yuma County, Arizona.
