SODIUM SULPHIDE ( Na₂S.xH₂O )

Sodium Sulphide is a co-product in the manufacture of Barium Carbonate. The solution of Sodium Sulphide obtained from the process is concentrated to 6-18% and is available at different percentages in tanker loads. It is also converted into Flakes / Solid of different purities ranging from 52 - 60%, depending on the customer's requirement.
