- Canisters
The concentration and packaging can be selected according to the specific application and logistical requirements.
Applications
Due to its chemical properties, sodium sulphide is an important raw material and process chemical for numerous industrial applications. Key areas of use include:
Mining and Metal Processing
Sodium sulphide is used in ore processing and metal extraction. Among other applications, it is used in flotation processes and in the treatment and separation of certain metal compounds.
Leather Industry
In the leather industry, sodium sulphide is primarily used in the dehairing of animal hides. It supports the removal of hair and prepares the hides for subsequent processing steps.
Chemical Industry
Sodium sulphide serves as a raw material and process chemical for various chemical processes and is used in the production and processing of other sulphur compounds.
Wastewater Treatment
In industrial wastewater treatment, sodium sulphide can be used for the chemical precipitation of certain heavy metals. Insoluble metal sulphides are formed in the process and can subsequently be removed from the wastewater.
Other Industrial Applications
Sodium sulphide is also used in a range of other industrial processes, including the treatment of inorganic and metal-containing process streams.
Quality and Reliable Supply
With decades of experience in the production of sodium sulphide, we offer our customers consistent product quality, different concentrations, flexible packaging options and reliable supply.
