Chemistry Multiple Choice Questions on "Concentration of Ores". 1. Concentration of ores is also known as ore-dressing. a) True b) False Answer: a Clarification: The removal of unwanted earthy and silicious impurities (that is, gangue or matrix) from an ore is called concentration of ores. Concentration of ores is also …
One of the processes used for concentration of ores is Froth floatation process. This process is generally used for concentration of sulphide ores. Sometimes in this process we add NaCN as a depressant. NaCN is generally added in case of ZnS and PbS minerals. What is the purpose of addition of NaCN during the process of Froth floatation ?
Fig. 1 shows the particle-size distribution of the iron ore jigging tailings sample and the concentration feed sample (grinding/classification at 1.4 mm). As observed, the d 80 of the tailings sample is approximately 4000 μm (4 mm) with only 4% of the particles below 37 μm (0.037 mm). The d 80 of the concentration feed sample is 840 μm (0.840 …
Froth Floatation method is the method used for the concentration of sulphide ores. The method is based on the different wetting characteristics of the gangue and the sulphide ore. Calcination: The ore is heated to a high temperature below its melting point in the absence of air or in a limited supply of air.
The various processes for the concentration of various types of ores are as follows. Hand-picking; It was the traditional system of directly concentrating ore with the hands. With the use of a hammer, the gangue or adhering solid matrix is removed from the ore in this procedure. The separation and identification of gangue are based on colour or ...

Concentration Of Ores. Generally, the ores are associated with nonmetallic impurities, rocky materials and siliceous matter which are collectively known as gangue. The preliminary step in metallurgical process is removal of these impurities. This removal process is known as concentration of ore.
The concentration of the ores varies on the amount of metal and gangue present in the ore, and the methods used for the concentration of ore depend on the chemical and physical properties of the ore. There are four basic methods for enhancing the concentration of the ore, leaching method, gravity separation, froth floatation method, …
The QEMSCAN (Table 1) shows that ore S is composed of serpentine, goethite, siderite, spinel, quartz, olivine and clays (nontronites and saponite), and nickel is mainly associated with serpentine, goethite and clays.On the other hand, ores L and I contain mainly spinel, goethite and quartz, with less concentration of serpentine, …
