To reduce NaHS consumption, nitrogen or inert gas is used as the flotation gas supply. The Delany Patent (1972) showed that using inert gas or nitrogen rather than fresh air can cut the NaHS consumption in half. Nitrogen was first tested in enclosed WEMCO cells for byproduct molybdenum flotation at Anamax Mining Company in 1983.

A strong dependence of flotation on pH is evident from this figure. Maximum flotation is obtained around the neutral pH range and this is in agreement with the results reported in the literature [10].
