Sodium sulfide has many grades, depending on different Fe content. For some customers, they require a relative low Fe percentage, like 10 ppm max, especially in copper ore dressing, sulfur dyes and leather industry. Recently, we have exported 1FCL=15mt Sodium Sulfide 60% flake Fe 10ppm max (500KG Jumbo bag packing) to Malaysia. We are fully confident of the situation and future development of the copper mining industry in Malaysia.
