CBSE Class 12 : Different methods of concentration of ores

Different Techniques for Ore Concentration: The following processes are used for the concentration of various types of ores. Hydraulic Washing; The difference in gravity of the gangue and ore particles is the basis for it. As a result, it is categorised as a gravity separation method. The powdered ore is washed using an upward stream of Worldwide there are over 43 million artisanal miners in virtually all developing countries extracting at least 30 different minerals. Gold, due to its increasing value, is the main mineral extracted by at least half of these miners. The large majority use amalgamation either as the final process to extract gold from gravity concentrates or from the whole ore.

The energy needed to concentrate minerals from common

The specific energy was equivalent to 151 MJ/t of ore. This figure was more than twice the average value of electricity consumption at a concentration copper plant in Chile for 2015 (80.8 MJ/t ore) as reported in Ref. [ 71 ]. If the specific energy is expressed by a ton of metal concentrate, this value was 34278 MJ/t.Following are the Physical Methods of concentration of Ores. i) Hydraulic Washing As the name suggests it is just simple washing of ore with water.

The powdered ore is agitated with water or washed with running stream of water. The heavy ore particles and lighter impurities are separated. This method of concentration is known as (a) metallurgy (b) leaching (c) froth floatation process (d) gravity separation. Answer. Answer: (d) gravity separationMethods of Enrichment. Hand Picking This is a traditional method where the impure solid matrix identified by their colour is removed with the help of a hammer. Hydraulic Washing In this method, the ore is finely ground and washed with water.

Concentration of Ores Class 12 Chemistry MCQ Sanfoundry

2 天之前Explanation: Concentration by hydraulic washing requires the ore particles to have a higher mass compared to its gangue particles. Hydraulic washing can be used for oxide ores of iron and tin such as haematite and tinstone and also for native ores of silver and gold. Pyrolusite is concentrated by magnetic separation.This is also called gravity separation or hydraulic washing and is generally used for oxide ores and carbonate ores. This method is based on the difference in densities of the ore particles and impurities. For example, haematite, tin stone and native ores of Au, Ag etc. which are usually concentrated by this method. 2) Froth-Floatation:Concentration of ores. Sarthaks eConnect Largest Online

Hydraulic washing is a technique used for the concentration

Solution. The correct option is B Gold. Hydraulic washing is a technique used when the impurities are lighter and the ore particles are heavier. The lighter impurities are removed by washing in current of water. As gold particles are heavier than the impurities like sand, we can use hydraulic washing for the concentration of ores of gold.Contribute to chengxinjia/sbm development by creating an account on .sbm/sbm why copper ore is not concentrated by hydraulic washing

Which Of The Following Ore Is Concentrated By Leaching

What type of ore is concentrated by hydraulic washing? Copper is mainly extracted from copper pyrites. After the concentration of its metal by froth flotation process, the metal is cooked in a current of air to eliminate arsenic, antimony and quite a bit of sulphur. The ore being sulphide mineral is concentrated by foam floatationIn hydraulic washing, an upward stream of running water is used to wash the powdered ore. The lighter gangue particles are washed away and the heavier ore particles are left behind. The method is also referred as Gravity Separation (ii) Magnetic Separation : Principle : The method is based on differences in magnetic properties of the Doubt Solutions Maths, Science, CBSE, NCERT, IIT JEE, NEET
