Iron Ore Wash Water Spiral . Effect of wash water on the mineral size recovery curves. Jun 10, 2014 This paper uses the mineral size recovery curves to investigate, using a 2 3 factorial design, the effect of the slurry solid concentration, slurry feed rate and wash water addition on a WW-6 spiral processing an iron ore. ...
The aim of this study is to investigate the effect of feed rate, solid concentration and the wash water on grade and recovery on iron ore material. The Multotec SC20HC/7 WW spiral was used for the experimental test work. The spiral was tested at varying solid …
Its flushing water pressure is less than 147-196kpa. Our spiral washing machine is suitable for the pre-cleaning of silt in iron, manganese, limestone, tin ore and other ore with a large amount of mud, especially for processing difficult-to-wash ore with medium grain size and more mud. Because This kind of ore washing machine has strong cutting ...
Recent developments in spiral and spiral plant technology include: • the launch of the VHG spiral model, speci fi cally aimed at feeds with very high levels of high-density mineral particles; • the introduction of a high capacity wash water spiral model; and • innovations in feed stabilisation and control.
Feed size is usually between1.16 mm and 74 μm (14 and 200 mesh), but with iron ore, up to 2.3 mm (8 mesh) material may be treated to make a rougher concentrate, provided a high pulp density is used. Solid content of approximately 15-35% solid concentration combined with wash water produces good results.
Capacity: 0.15-10t/h Feeding size: 0.02-0.3mm Application: fine-grained gold, iron, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphorite, tungsten ore, tin ore, tantalum-niobium ore, minerals with different specific gravity, other non-ferrous metals, rare metals and non-metallic minerals separation; and also be used for placer mining on seashores, …

Spiral Classifier. Capacity: 21-1785 t/24h (over flow); 145-23300t/24h (returned sand); Up to 150% spiral submergence. Spiral diameter: 500-3000mm; Single, double or triple pitch spirals are available. Application: …
Add a high-pressure water flushing device on the fixed screening machine. The flushing water pressure is generally 0.2-0.3 MPa, and the water consumption per ton of ore is 1 ~ 2 m3. When the raw ore contains little mud and the cohesiveness is not strong, the use of such combination can meet the requirements of washing. 3.
A series of tests were conducted using an iron oxide ore to analyze the effect of the wash water addition, spiral slurry feed rate and solid concentration on a …
Commonly used chrome ore washing equipment include hydraulic ore washing sieve, cylindrical ore washing machine, trough ore washing machine, plane sieving machine and spiral classifier. Chute can also be used to wash ore. The hydraulic ore washing sieve is a method of washing ore using a water gun to wash on a fixed …
Spiral concentrators are widely used in the iron ore industries to concentrate heavy iron oxides from light silica gangue minerals. The operation of a WW-6 spiral for the …
DOVE Spiral Classifier, also referred to as Screw Classifier, or Spiral Mineral Separator, is highly efficient classifier designed for closed circuit wet classification and separation of the Slimes (Fines) from a sandy sized (Coarse) material. It is well suited for classification, where a two product size-split is required. Due to inherent operational qualities, DOVE …
Increasing the wash water flow rate increases the concentrate grade at the expense of the iron recovery.The paper addresses the effects of dripping wash water onto the …
Spiral concentrators are widely used in the iron ore industries to concentrate heavy iron oxides from light silica gangue minerals. The operation of a WW-6 spiral for the concentration of an iron oxide ore is analyzed through the size recovery or partition curves of the minerals. Several tests conducted following a factorial design using wash water …
Effect of wash water on the recovery of coarse hematite in the concentrate of a test spiral [6]. in Chemical Engineering and Science decrease in the wash water addition will reduce the iron ...
Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and heavy mineral ores (Wills, 1992). Gravity concentration remains the main separation method for fine iron ore and is used extensively for treating many minerals. Gravity concentration methods separate minerals of different specific gravity by their …
A spiral classifier is shown in Fig. 1.The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.Dense hematite particles slide toward the inner part of the …
feederate, solid concentration and the wash water on grade and recovery on iron ore material. The Multotec SC20HC/7 WW spiral was used for the experimental test work. The spiral was tested at varying feed rate and solid concentration, the wash water rate was also varied to establish the best washing rate.
The paper addresses the effects of dripping wash water onto the concentrate stream of a spiral processing fine iron ore. The dripping wash water system offers a low flow …

Minerals mined in Australia include iron ore, coal, gold, copper, nickel and zinc. Spiral concentrators are used in mineral processing for separating minerals. Multotec Australia has a range of gravity concentration equipment for effective mineral concentration. The range comprises end-to-end spiral solutions, from process audits and test work ...
The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …
Thus, the obtained gangue mineral model is only valid for relatively high wash water flowrates, which are greater or equal to 6 Lpm. A coarse particle recovery decrease has been previously observed for iron ore treatment in spiral concentrators [11,13,26,27]. This phenomenon has been attributed to the Bagnold force, which preferentially acts on ...
