Chemical appearance:
The appearance of Sodium metabisulfite is either in the form of white crystals or as a powdered solid with a slight odor of sulfur. Inhalation could lead to toxic results and can cause serious damages to skin and tissue. Sodium metabisulfite is clearly soluble in water and forms a clear and colorless solution.
Chemical application and strengths:
The primary applications of Sodium metabisulfite are evident in the mining industry. It is used for controlling the depression of pyrites and sphalerite minerals. MBS is ideal for pH control for the froth flotation process, where it could control pyrite depression. Sodium Metabisulfite is also helpful in preventing flotation of sphalerite through copper activation with the availability of Tennantite/Covellite in the ore.
In the case of pyrite flotation, the maximum iron/pyrite depression with the use of Sodium Metabisulfite is possible somewhere around the pH of 6.

Potassium Butyl Xanthate is a reagent that plays a pivotal role in modern mining and metallurgy.
Flotation Process Facilitator: Potassium Butyl Xanthate is an indispensable ally in the flotation process, a cornerstone of mineral extraction. Flotation involves separating desired minerals from their ores.
Selective Adhesion: When introduced to a slurry of finely ground ore and water, Potassium Butyl Xanthate selectively adheres to sulfide minerals present in the mixture. These minerals, often hosting valuable elements like copper or lead, exhibit a unique affinity for the xanthate.
Bubble Attachment: Air bubbles are introduced into the slurry. The hydrophobic mineral surfaces coated with Potassium Butyl Xanthate collectors readily attach to the bubbles, effectively making them float to the surface.
Rising to the Top: The mineral-laden bubbles rise to the surface of the flotation cell, forming a froth layer.
