With other flotation implications of the mineralogical differences, the recovery of the two minerals cannot be maximized in the same pulp and the extent of increase in recovery obtained here can be considered satisfactory.
On the other hand, near-surface geochemical destruction of magnetic minerals cannot be completely excluded, and may contribute to local changes if such destruction takes place in the vicinity of measurement sites.
In the case of inert mineral admixtures, the increase in strength with the fineness of mineral admixtures cannot be explained by the filler effect, but can be attributed to the physical effect of heterogeneous nucleation.
The authigenic ultrafine quartz grains (d90 = 15.8 μm) closely associated with this CSK sample was the major impurity mineral, which cannot be separated from kaolin by screening and size classification process.
Under these regulations natural mineral water cannot be sterilised or otherwise treated to destroy microorganisms.
Similarly to vitamin intakes, also mineral intakes cannot be compared directly to the results of other studies because of the age differences among the studied populations of children.
If breast milk energy macronutrient and mineral content cannot be directly analyzed for the individual mother and infant, the average values from these meta-analyses may provide useful estimates of the milk content.
When breast milk energy, macronutrient and mineral content cannot be directly measured the average values from these meta-analyses may provide useful estimates of mother's milk energy and nutrient content.
Furthermore, the possibility that the chloroform fumigation-extraction method causes an underestimation of the amount of microbially-bound 137Cs in "mineral" soil samples cannot be completely ruled out.
When transposed in situ, our method performed successfully at 20 ± 2 °C and at 8 ± 2 °C as well and it could be a better choice than the previous demoulding methods like those using vegetable oils, developed recently to replace mineral oils, they cannot be used at low temperatures.
