Sodium hydrosulfide - Wikipedia. Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) with sodium hydroxide.NaHS is a useful reagent for the synthesis of organic and inorganic sulfur compounds, sometimes as a solid reagent, more often as an aqueous solution.

The effect of sodium hydrosulfide on molybdenite

2020-3-15  Diesel oil was added in flotation without dilution while MIBC was diluted to 1 wt%. The pH was adjusted by the addition of 1 M NaOH solution instead of lime commonly used in flotation plants to eliminate the effect of Ca 2+ on the flotation. Sodium hydrosulfide (NaHS) was added as a depressant in the flotation. Both NaOH and NaHS were of AR grade.
