This lead and zinc ore dressing plant adopt flotation method. The capcity is 600t/d for one line. The equipment includes 2 sets of grate ball mills and spiral classifiers, 24 sets of mechanical agitation flotation cells, 4 heavy duty agitation tanks. This kind of design is simple (little wear parts), robust, high working efficiency,  low […]

Fineness is the operating index of the grinding and classification process of the ball mill, and the fineness of the discharge and classifier overflow and coarse sand return should be measured frequently in the ore dressing plant or froth flotation plant in order to adjust the operation in time. The rapid sieve analysis method commonly […]

Froth Flotation

froth flotation is an important method for separate the minerals from the ore. first we crushing and grinding the ore to be proper size like 0.074 mm less than 80% by a wet ball mill. Then we feed the ore slurry in the agitation tank where the frother, collector and dispersing agent is added by […]

CIP or CIL gold processing plant in africa by ZJH minerals

Take the follow 6 steps for help you design and build a high efficiency CIP or CIL gold processing plant to extract gold from the gold ore. 1. The concept of CIP or CIL gold processing plant 2. The application of CIP or CIL gold processing plant 3. Confirm the capacity 4. Design the flow […]

flotation reagents dosing peristaltic pump

Flotation Reagents Dosing peristaltic pump plays an irreplaceable role in the precise  flotation reagents dosing. Flotation agents modify mineral surface properties, increase or decrease mineral floatability, and make pulp properties and foam stability more favorable for mineral separation. The flotation reagent is adopted in the ore dressing industry, and the variety is the most, and […]

Beneficiation test of gold ore

According to the requirements of the mine owner, the six samples were combined into three kinds of raw ore samples in pairs.  Then the three kinds of raw ore were crushed to -2mm and mixed, then the samples were taken out for testing sample and stored separately. The contents of Au, As, S and other […]

Froth Flotation Process

Froth flotation process is an efficient mineral concentration method  in minera processing industry.  The raw ore is crushing, grinding and classification (spiral classifier or hydrocyclone) to be for getting the proper size and density ore pulp. The ore pulp goes into the agitation tanks,  where the flotation reagent is added for treating the surface of […]

Lithium Mineral Flotation

Lithium Mineral Flotation is important method for getting lithium minerals (spodumene, petalite and lepidolite) from hard-rock resources. ZJH minerals supply the whole set of equipment for Lithium Mineral Flotation, most notably for spodumene. Spodumene theoretically contains 8.03% Li2O and therefore the production of this mineral is greatly increasing, especially demand for electric vehicle batteries. The […]

Gold Extraction Methods from different types of gold ores

Gold extraction methods include shaking table method, spiral chute, flotation, heap leaching, CIP or CIL ,Bio-oxidation , etc. Different types of gold ores shall adopt different kind of gold extraction method. 1.  Gold ores from gold-bearing quartz veins Mineral composition of this gold ore is relatively simple. Gold is the only mineral for collection. The […]

Bio-oxidation Reactor

Bio-oxidation reactor is used for biological oxidation of refractory gold concentrate containing pyrite or arsenopyrite. Gold concentrate after regrinding, magnetic removal of iron, thickening and removal of reagents, according to the proportion , adding water, sulfuric acid and biological media,feeding into the slurry agitation tanks, adjusted into a solid concentration of 16%- 25% pulp, which […]
