• #### Flotation Circuit: Concentrate Grade and Recovery MinAssist

The texture of particles within a flotation cell play a pivotal role in both mineral recovery, and the grade, in the flotation concentrate. Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum grade-recovery possible for a given feed ore.

For wheel (or post) spacings of 5' to 15', the increase in stress is

• 2020-6-25 Occasionally the calculation of the grade of perfect concentrate is unnecessary because the smelter may prefer a certain maximum grade. For example, a perfect copper concentrate for an ore containing copper only as chalcocite would run 79.8% copper, but if the smelter is best equipped to handle a 36% copper concentrate, then for

• The formula can vary but is often only based upon p. Other factors can be included such as recovery to concentrate and net concentrate value. We will use volcanic-hosted massive sulphide deposits 1 (VMS or VHMS) as an example because the use of “equivalent grade’ is unfortunately familiar in this type of deposit. By way of comparison

As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately \$6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).

Since 1 liter of water has a mass of 1 kg, any concentration expressed in mg/L is already in PPM because it’s equivalent to mg/kg. So if you have a mixture of 132 mg/L, then it’s 132 PPM, and you can even perform simple conversions from things like g/L to PPM by using this fact (just convert the mass to mg and you’re done).
