In South Africa, Liming heavy industry has the larger scale customers’ site and best service for the iron mining investors.
We are leading Iron ore beneficiation plant equipments manufacturer, and provide complete set of iron ore processing equipments. iron ore beneficiation plant is mainly consisted of circular vibrating screen, pendulum feeder, vibrating feeder, belt conveyor, flotation Machine, magnetic separator, high gradient magnetic separator, spiral classifier, European type jaw crusher, ball mill, spiral chute, mining stirred tank, sand washing machine, spiral washing machine, rotary drier, indirect heat drier, concentrator, dust collector, coal classifier, etc.

iron ore concentrate beneficiation technological process:
Iron ore fines reclaimed from the blending stockpile shall be conveyed into a surge bin within the beneficiation plant building. Ore drawn from the surge bin by a belt weigh feeder is fed to a spiral screw type classifier.
Washed ore from spiral classifier is screened for +4 mm and -4 mm fractions over a scalping screen. Undersize fraction of -4 mm is pumped to sizing screens for screening off -1 mm fraction. Oversize fractions of +4 mm from the scalping screen and +1 mm from the sizing screens are ground in a primary ball mill in closed circuit with sizing screens to get 100% -1 mm solids suitable for gravity separation in spirals.

Washed sizing screen underflow fraction of -1 mm is pumped to dewatering cyclones. Underflow of dewatering cyclones is beneficiated by gravity separation through two stage spirals viz., rougher and cleaner spirals. Concentrate from spirals circuit is ground to a size consistency of 100% passing 100 mesh and ~70% passing 325 mesh in secondary ball mills in closed circuit with classifying cyclones. Ground concentrate from the classifying cyclones overflow as well as the overflow from dewatering cyclones ahead of spirals are pumped to concentrate thickener. Concentrate thickener underflow is thereafter filtered to get a product with 8% moisture max. The filter cake is conveyed to stockpile.
Tailings from high gradient magnetic separators is fed to tailings thickener.
Spiral classifier overflow is pumped to de-sliming cyclones. Overflow from these de-sliming cyclones is fed to the tailings thickener. Underflow from de-sliming cyclones is diverted to spiral tailings pump box in turn to high gradient magnetic separators to recover Fe units as much as possible.Tailings thickener underflow is pumped to tailings settling pond.

Beneficiation includes selection of effective crushing and grinding technologies, wet and dry beneficiation, and the control of moisture levels in material.
A wet beneficiation plant for producing high-grade iron ore concentrate requires screens, grinding Mills, spirals, magnetic separators, Agitators, Floatation, Filters and thickeners.
Of course, we also supply best after-sale service, if you want to invest iron beneficiation, please leave me your email to [email protected] or chat online.
