Pure zinc sulphide is white in colour and is used as white pigment.
But it is usually black in colour due to the presence of impurities.
The zinc sulfide is ZnS.
Zinc is obtained from zinc blende/sphalerite ore (zinc sulphide)
fungicide
ZnSO4

zinc chloride +amonium sulphide=
black smokers are hydrothermal vents emitting sulphides such as iron sulphide, zinc sulphide, copper sulphide etc Which are black in color hence called black smoker.....there are white smoker which emit sulphates like barium sulphate and gypsum(CaSO4) which are white and there the name white smoker.
Zinc Sulphide or strontium aluminate is the 'active ingredient'
Zinc forms a compound with sulphur. it gives zinc sulphide, known as the mineral zinc blende or sphalerite. Hope I helped:) ^_^
Zinc sulphide has the chemical formula ZnS.
Most zinc is recovered from zinc sulphide ore that also contains sulphide of other metals as well as silicon dioxide and perhaps other materials. Physical methods are used first to eliminate some of the undesirable substances then the ZnS is heated to recover the zinc. For more details please see the wikipedia article for zinc.
