In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material
Up to now, with 2000 servied mine projects, 500 mineral processing EPC+M+O projects, 70 kinds of ores mining technologies and experience and 112 patents, Xinhai has established multiple overseas offices in Asia, South America and Africa and exported to more than 90 countries and regions.
Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.

Hongji Group Product Superiority. Spiral classifiers or screw classifiers are important ore dressing equipment. Spiral classifier is mainly used in metal beneficiation production line to classify minerals according to their different sedimentation velocity. Screw classifiers can be divided into high weir type, low weir type and sank type according to the height of the weir.

The slime fraction of the ore overflowed by the hydraulic classifier and by the rod-mill spiral classifier is thickened in a Spiral Rake Tray Thickener for treatment by flotation. The flotation circuit is designed to treat three classes of manganese ores. Those ores with a high calcite gangue. Those ores with mixed calcite and siliceous gangue.
Classification refers to sizing operations that exploit the differences in settling velocities exhibited by particles of different size. Classification equipment may include ore sorters, gas cyclones, hydrocyclones, rotating trommels, rake classifiers or fluidized classifiers.
The Double Spiral Classifier / spiral classifiers are divided into single spiral classifiers and double spiral classifiers. If the overflow edge is higher than the center line of spiral shaft and lower than the external diameter of spiral at the overflow end, the spiral classifiers are high weir ones.
Each mineral processing plant is different: with varied ore types, mining equipment, and management (operating) philosophy. The evaluation and prioritisation of variables that affect the plant performance is the primary function.

Xinhai provides mineral processing technology, equipment manufacture and one-stop service for mineral processing plant, which solve many problems for mine investors. Xinhai equipment mainly include: ball mills, flotation, thickeners, and so on.
This concentrate is therefore very low grade, from the milling point of view, running only 77.6% of perfect grade. On the other hand, the low sulphur assay of concentrate B shows this to be a marmatite, for 10% iron occurs in the form of FeS and only 2.5% iron as pyrite.
Hongrun Mining Machinery is a professional mining equipment manufacturer which has more than 20 years experience in ore dressing equipment and solutions. Our main equipment: crusher, ball mill, dryer, rotary kiln, magnetic separator, shaking table, etc. Welcome to Hongrun.
Flotation separation process. The flotation separation process also known as the flotation separating production line realizes the mineral particle separation based on the working principle of different physical and chemical properties of the minerals leading to different floatability.
Two saprolitic ores from two different mining areas (Sulawesi Island and Halmahera Island) in Indonesia were used to investigate the leaching performance and mineral dissolution behaviors of different ore samples using different leaching reagents. Leaching was performed using citric, sulfuric, nitric, hydrochloric, lactic, and oxalic acids.
ORE TRACKING: Mining equipment implemented for ore extraction is optimal for selective mining. Material from the pit is transported to various stockpile destinations. These include high-grade (>13% Zn), medium-grade (9 13% Zn), low-grade (4 9% Zn) and marginal (1 4% Zn) ore stockpiles. Limestone (Ca >28%) from the pit is mined for plant acid

A biomining approach to process low-grade iron ores has the potential to turn closed mines or uneconomic mineral deposits into economic resources. Microorganisms and their metabolites have been commercially applied in the leaching of metals from medium- and low-grade
The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up the incline to the discharge.
The spiral classifier also named the screw classifier or the spiral classifier machine works as a type of sand classifier or screw sand washer by using the working principle of materials with different particle sizes and weights tending to sink in the liquid at different speeds.
The ore samples were supplied from a new low-grade chromium ore deposit located in Eastern Anatolia in Turkey, and they were characterized in detail in terms of their physical, chemical, and
Introduction. The iron ore beneficiation plant and the iron ore concentrate quality of our company has reached the international advanced level, but considering the Chinese iron ore features of deficiency, impurity and fineness, our company, as a leading iron ore processing line manufacturer, should not only promote the advanced iron ore beneficiation plant (including the flotation iron ore
Magnetic separation process. The magnetic separation process, also named the magnetic separating production line and made up of jaw crusher, ball mill, classifier, magnetic separating equipment, concentrator and dryer, is a wet and dry separation combination method of magnetite.
May 15, 2016 A typical spiral classifier is shown in Fig. 1.The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough ().The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.
