no.

At a density of 1.07 kg/m3 for feed brine there was
1.07x.503x100=53.82 kg K in 10,000 litres

% K in total harvest is Initial K x %recovery
----------------------
potash harvest weight

= 53.82x.875
----------
983

= 4.8% K = 10.95% K2SO4


which means at a $500/t sale price each tonne of harvest
salts to be removed by the potash harvester has a SOP
contained value of
.1095x 500
= $54.75/tonne

so % K is very important as you want to be handling
the highest value/tonne possible at harvest time to maximise
profitability.
