Ore Beneficiation Process

As one of the leaders of mineral processing industry in the world, Xinhai firstly gained Class-A design qualification, and possessed mine design institute and beneficiation research institute to provide technical support for mineral processing service, aiming at customizing professional mineral processing process for each mine and help customers to maximize mineral processing benefit.

Mineral Processing Equipment

During more than 20 years, Xinhai has always been at the forefront of global ore concentration industry, and constantly devoted itself to the research and innovation of mineral processing technologies and equipment. After many years of study, we have independently produced a series of efficient and energy saving ore beneficiation equipment, which helped our global customers finish mineral processing EPC projects one by one.

    • Energy Saving Ball Mill


      A high efficiency and energy saving ball mill with rolling bearing


      √ Energy saving ball mill is lined grooved ring plate which increases contact surface between ball and ore, strengthens the grinding effect.

    • Overflow Type Ball Mill


      A ball mill with simple structure


      √ The cylinder is lined with super wear-resistant rubber sheet, excellent wear resistance, long service life and convenient maintenance.

    • High Weir Spiral Classifier


      It takes use of different sedimentation speed of solid particle in slurry.


      √ Add automatic elevating apparatus to discharge opening; Eliminate scoop of ball mill, more stable motion.

    • Hydrocyclone


      A hydrocyclone with advanced involute feeding


      √ Adopting unique involute feeding increases material centrifugal force, improves classification effect and reduces feed box wear.

    • Flotation Cell


      Xinhai sucessfully developed air-inflation agitation type and mechanical agitation type floatation cell.


      √ Xinhai flotation reagents enhance the mineral surface hydrophobicity, mineral adhesive fastness and improve more 25% mineral flotation speed

    • Gravity Separation Equipment


      jig, concentrating table, spiral chute


      √ Jig adopts cone slide valve, the failure rate is reduced by 80%;
      √ Concentrating table adopts cam lever type head, which is easy to adjust stroke.

    • Magnetic Equipment


      magnetic drum, magnetic separator, dry magnetic separator


      √ Less than 180° warp angle design,increases magnetic turn degree;
      √ Magnetic materials adopt ferrite and NdFeB with high performance, high coercive force.

    • Gold Extraction Equipment


      leaching agitation tank, desorption electrolysis system, washing thickener, carbon screen, zinc powder displacement device, air lifter


      √ Xinhai high-temperature and high-pressure desorption (150℃,0.5Mpa) can desorb 99% gold within 2-6 hours.

    • Efficient Improved Thickener


      Self-developed new efficient thickening equipment


      √ This thickener is patent product of Xinhai with larger capacity, lower overflow turbidity and higher discharge concentration.

    • Efficient Deep Cone Thickener


      An independently developed deep cone thickener, underflow concentration is up to 70%


      √ Large angle cone, high underflow concentration;
      √ Small occupied area, high automation level and electricity saving.

    • Ceramic Filter


      Vacuum dewatering filter by relying on microporous ceramic


      √ Microporous ceramic as filtering medium, saves 90% cost;
      √ High vacuum degree (-0.09~-0.098MPa), low cake moisture.

    • Drum Filter


      traditional external filtration type vacuum filter


      √ Realizes stepless speed change by adjusting motor revolution;
      √ Simple structure, low price, convenient operation and little wearing parts.
