Barite ore processing continuously generates solid tailings waste and processing effluent. Tailings treatment involves the establishment of a comprehensive process system centred on four key areas: effluent recycling, solid waste storage, ecological restoration and resource recovery, whilst balancing production stability with green production requirements.
Barite separation relies on three key differences—density, surface physicochemical properties and magnetic properties—to form three core processes: gravity separation, flotation and magnetic separation.
Gold ore separation is primarily based on the mineralisation characteristics of the ore, with gravity separation and flotation being the two fundamental separation methods.
Chemical purification of quartz is divided into two main processes: direct acid leaching and ammonium salt activation roasting followed by acid leaching. These processes are designed to address the inability of physical purification methods to remove lattice aluminium, iron and silicate impurities, thereby enabling the production of ultra-high-purity quartz.
Deep underground gold mines are characterised by confined working spaces and complex geological stresses; traditional manual operations pose numerous safety hazards. Full-process automated equipment has therefore become the key means of enhancing quality and ensuring safety underground,
As a core strategic mineral in the fluorine chemical industry, fluorite is associated with a wide variety of gangue minerals. Quartz, calcite, barite, sulphide minerals and clay minerals can all interfere with the purification of fluorite; it is difficult to consistently produce high-grade fluorite concentrate relying solely on a single process or a single reagent.
Various types of lithium ores, such as spodumene and lithium mica, exhibit complex mineralisation patterns and are often accompanied by impurity minerals such as iron, tantalum and niobium. To efficiently separate lithium minerals and produce qualified lithium concentrate, the complete production line is divided into four core stages: crushing and screening, grinding and classification, combined multi-process beneficiation, and concentrate thickening and dewatering.
The entire process is divided into three main parts: the lead flotation circuit, the classification and enrichment unit, and the zinc flotation circuit. The entire process adopts the core principle of prioritising lead flotation followed by zinc recovery from the tailings, combined with a differentiated reagent system to achieve efficient separation of lead and zinc.
Rock gold ores come in a wide variety of types, with significant variations in grain size and associated minerals. Many mines face challenges such as low gold recovery rates and persistently high production costs due to the selection of inappropriate processing methods. In fact, different rock gold ores possess unique mineral characteristics; by matching them with dedicated separation processes, metal recovery efficiency can be significantly improved
In graphite mine beneficiation, the physical properties of different types of graphite minerals vary greatly, and the challenges faced in beneficiation are entirely distinct: large-flake graphite is prone to breakage and wastage, fine-grained graphite is difficult to separate, and crystalline and microcrystalline graphite is difficult to liberate.
