Methods of enrichment of ore: Now, we shall discuss the different processes which are used for enrichment of different types of ores. 1. Hydraulic Washing This method is used for the enrichment of those ores which are heavier than gangue particles present in them. In this method, a stream of water is passed through crushed and finely powered ore.
Hydraulic washing: It is based on gravity differences between the ore and the gangue particles. In one such process, the lighter gangue particles are washed away by a stream of water, leaving behind the heavier ore. FrothFloatation method: This method is applied to remove gangue from sulphide ores.
Concentration of ore . · Hydraulic washing of the ore Hydraulic washing is a type of gravity separation, which is based on gravity differences between the ore and the gangue particles. In this process, the lighter gangue particles are washed away by a stream of water, leaving behind the heavier ore.
The ore which was supplied in lumpy form was subjected to crushing and grinding. The ore was ground to 70% passing 75 microns. Chemical analysis of this ore is shown in Table 1. 1% solutions of all flotation reagents collector (SIPX sodium isopropyl xanthate) and depressant (Betamin 300) were used for the investigations and 10% solutions of

Hydraulic Washing. This method is based on the differences in weight between the gangue and the metal. Generally, the metal particles of the ore are heavier than the impurities. So we use the principle of gravity separation to separate the two. Here crushed ore .
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air .

Different procedures for Concentration of Ores Hydraulic Washing. ... It is then dried for recovery of the ore particles. Sometimes depressants are used to separate the sulphide ores by adjusting the proportion of oil to water. Such as, in case of an ore containing Zinc sulphide and lead sulphide. The depressant used is sodium cyanide.

Copper ore, usually in the form of malachite, needs to be refined through a chemical reaction, rather than a mechanical separation as with washing. It needs to be ground and heated to separate out ...
Introduction to Mineral Processing. Froth Flotation Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer ...
what is1 Hydraulic washing 2 FrothFloatation method 3 Leaching Chemistry ... Sometimes, depressants are used for separating two sulphide ores by selectively preventing one ore from forming froth. For example, NaCN is used as a depressant for separating two sulphide ores, ZnS and PbS. Leaching: The process of leaching is used, if the ore is ...
There are numerous methods of concentration and the methods are chosen based on the properties of the ore. Hydraulic Washing: This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation.

Ores: The minerals from which a metal can be profitably extracted are called ores. Metals found at the bottom of reactivity series are least reactive and they are often found in nature in freestate; such as gold, silver, copper, etc. Copper and silver are also found in the form of sulphide and oxide ores.

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
Jun 26, 2019· (b) Hydraulic washing or Levigation or Gravity separation: The separation is based on the difference in the specific gravities of the gangue particles and the ore particles. (c) Electromagnetic separation: When one component either the ore or impurity is magnetic in nature, this method can be used for separation.
