Concentration of Ores Study Material for IIT JEE

Gravity Separation or Hydraulic Washing (Levigation) This method of concentration of the ore is based on the difference in specific gravities of the metallic ore and gangue particles. Generally metal ores are heavier than the gangue associated with them. By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind. For

CHAPTER 7 METALLURGY EXERCISE 7B Question 1:Give the

(a) Hydraulic washing (b) Forth floatation (c) Electromagnetic separation Solution 1 (a) Hydraulic washing: This process depends on the difference in the densities of the ore and the gangue. (b) Forth floatation: This process depends on the preferential wettability of the ore

Important Questions for Class 12 Chemistry Chapter 6

Why is copper matte put in silica lined converter? (Comptt. Delhi 2012) Hydraulic washing (ii) Vapour phase refining (Delhi 2014) Answer: (i) Hydraulic washing or Levigation : The process is based on the principle that lighter earthy particles are removed from heavier ore particles by washing with water (Difference in the gravities). (ii) Vapour phase refining : In this method, the crude

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Copper Smelting Chemistry Tutorial AUS-e-TUTE

The concentrated (enriched) ore can contain up to 35% copper and a number of impurities such as antimony, arsenic, and lead. Roasting : reduces impurities in the copper ore and produces calcine (a mixture of products) * Concentrated (enriched) ore is heated to between 500 o C and 700 o C in air.

Copper Ore Types: Sulfides vs. Oxides An Investor's

Types of copper ore: Oxides. As mentioned, copper oxide ores are not as attractive an exploration target as copper sulfide ores due to their lower grade. However, in some cases low-grade copper

What is the Process of Metallurgy A Plus Topper

This process is also called hydraulic washing. (ii) Froth floatation : Sulphide ores of copper, lead and zinc are generally concentrated by this method. The finely powdered ore is mixed with water and a small amount of oil in a tank. Air is blown into the mixture. A froth or scum is produced at the surface. The ore particles are carried by the froth to the surface. The earthy impurities sink

copper extraction and purification chemguide

The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulphur

Metallurgy: Terminology, processes used in extraction of

A mineral containing a high percentage of metal from which the metal can be profitably extracted is called an ore. Ex: Copper glance (Cu 2 S), Haematite ( Fe 2 O 3). Ores may be divided into four groups . Native Ores: These ores contain the metal in free state eg. Silver gold etc. Oxidized Ores: These ores consist of oxides or oxy-salts (eg. carbonates, phosphate) and silicate of metal. e.g
