Lead oxide concentrate is widely utilized across multiple industries due to its distinctive physical and chemical characteristics. Produced through the beneficiation of lead-bearing minerals, these concentrates serve as essential raw materials in the manufacturing of sulfuric acid storage tanks, solder, cast components, and various products within the oil, petrochemical, enameling, paint, electrical, and battery sectors .The production process typically involves the extraction of lead ore from mines, followed by crushing and the removal of impurities using flotation or gravity separation techniques, and ultimately purification. Both lead oxide concentrate (PbO) and lead sulfide concentrate (PbS) are used in smelting facilities for diverse industrial applications. Their technical specifications are established in accordance with relevant industry standards.
Zinc concentrate is produced through the beneficiation of zinc ore and serves as an essential intermediate material in the production of refined zinc metal. It is generally categorized into two primary types: zinc oxide concentrate (ZnO) and zinc sulfide concentrate (ZnS). The production process includes the extraction of zinc ore, followed by crushing, grinding, and enrichment through hydrometallurgical or pyrometallurgical methods. During this stage, impurities such as lead, copper, and silver are removed to achieve the desired purity level. The quality of zinc concentrate is determined by factors such as ore type, zinc content, and the specific processing techniques employed. Concentrates are typically classified into three grades—low, medium, and high—based on their zinc content and overall purity.
