Recently, our institute's testing center successfully completed a comprehensive mineral processing trial targeting complex Canadian tailings resources after over three months of work. Commissioned by a long-term strategic partner, this trial aimed to efficiently recover multiple valuable elements—including cesium, lithium, rubidium, and tantalum—from the same ore sample while simultaneously separating quartz and feldspar.
Tungsten, a strategic metal renowned for its high melting point and exceptional strength, finds critical applications in aerospace, electronics, and high-end manufacturing. Extracting high-purity tungsten from natural ore to meet industrial demands is a meticulously precise process. Different types of tungsten ores exhibit distinct characteristics: wolframite boasts high grades but is scarce and difficult to locate; pyrochlore is abundant yet “reluctant” to yield, embedded in dense formations; while mixed ores present additional extraction challenges due to their complex composition.
With the gradual depletion of high-grade gold resources, low-grade gold deposits have become a key focus in current gold mining operations. However, such deposits typically exhibit challenges such as low gold content, fine-grained mineralization, and abundant impurities, leading to difficult processing and low recovery rates.
Ball mills are among the most critical grinding equipment in mineral processing production lines, with their operational performance directly impacting subsequent separation indicators. In gold and other metal ore processing, the proper selection and operational management of ball mills are of paramount importance.
Phosphate ore beneficiation methods are diverse, with the globally prevalent techniques currently including flotation, scrubbing and desliming processes, gravity separation, and calcination-digestion processes. With technological advancements, electrostatic separation, bioleaching, chemical beneficiation, and combined applications of multiple processes are also becoming increasingly widespread.
Transforming copper ore into qualified smelting feedstock requires a systematic and efficient mineral processing workflow. Given the generally low copper grades in natural ores, enrichment through scientific mineral processing is essential.
Tungsten and tin often occur together in the same ore deposits in nature as either symbiotic or associated minerals, making tungsten-tin separation a critical technical challenge in polymetallic ore processing.
Depending on ore properties and process conditions, cyanidation has evolved into multiple specific applications in industrial practice. Among these, cyanide-carbon-in-pulp (CIP), heap leaching, and stirred cyanidation represent the three predominant process routes currently in use.
lithium, a critical metal in the new energy era, relies on advanced beneficiation processes for efficient extraction. The beneficiation of hard rock lithium ores—mainly composed of minerals such as spodumene, lepidolite, and petalite—often requires "tailored" process flows based on ore characteristics.
As a vital non-metallic mineral, barite undergoes various beneficiation processes tailored to ore properties and production requirements. Current mainstream methods include heavy medium separation, jigging, shaking table separation, and flotation.
