What is the difference between ore mineral and gangue mineral?
Ore minerals are valuable minerals that contain essential elements or compounds, which can be extracted and processed for economic gain, such as gold, copper, and iron. In contrast, gangue minerals are the unwanted materials or impurities that accompany ore minerals in a deposit, often comprising silicates, carbonates, or other non-metallic minerals. The primary distinction lies in their economic significance, with ore minerals being sought after for extraction, while gangue minerals are typically discarded during processing.
What is the substance which reacts with gangue to form a fusible mass which can easily be removed?
The substance that reacts with gangue to form a fusible mass is called a flux. Commonly used fluxes include substances like limestone (calcium carbonate) or silica, which combine with impurities in the ore to create slag. This slag can be easily removed during the metallurgical process, facilitating the extraction of the desired metal. The use of flux is essential in processes like smelting to improve efficiency and yield.
What metals are extracted by froth flotation technique?
Froth flotation is commonly used to extract sulfide ores of copper, lead, zinc, and nickel. These metals are typically extracted from their ores by creating a froth that selectively separates them from the gangue materials.
What are impurities of an ore called?
Gangue-In mining, gangue(pronounced "gang") is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed.
How is Coltan concentrated?
Coltan is typically concentrated through a process called gravity separation, where the ore is crushed and then subjected to gravity-based methods to separate the heavier coltan minerals from the lighter gangue minerals. Another common method is magnetic separation, where coltan-bearing minerals are separated based on their magnetic properties. These processes help to increase the concentration of coltan in the ore for further processing.
What is the relationship between mineral ore and gangue?
Mineral ore is the valuable material that can be extracted and processed for its useful properties, while gangue is the unwanted material that is typically separated from the ore during the extraction process. Gangue does not have any economic value and is usually discarded as waste material. The relationship between mineral ore and gangue is that they are often found together in the same rock or ore deposit, with the goal of separating the valuable ore from the gangue to extract the desired minerals.
What is the waste material that must be separated from an ore?
The waste material that must be separated from an ore is known as gangue. Gangue is the material that does not contain any valuable minerals and is typically removed during the process of ore extraction and purification.
What is the homophone of gang?
The homophone of "gang" is "gangue".
Why is gangue cosidered an ore?
Gangue minerals are not considered ores because they do not contain valuable minerals that can be extracted profitably. Ores, on the other hand, contain valuable minerals in high enough concentrations to be economically recovered. Gangue is typically separated from the ore during the mineral processing stage.
What waste rock must be removed before a mineral can be used?
Overburden and gangue are the waste rocks that must be removed before a mineral can be used. Overburden refers to the unconsolidated material above an ore deposit, while gangue is the unwanted rock in an ore deposit that has to be separated during processing.
Why is gangue rock reprocessed?
because it can be used in industrial ways
What is flotate in?
Flotation is a process of separation of an useful mineral from gangue.
What waste rock can be removed before a mineral can be used?
Gangue
What are two conditions which could occur to cause gangue to br reclassified as an ore?
In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. The separation of gangue from minerals can be a major obstacle. The ore may also be crushed to a fine grain.
Why is gangue sometimes reprocessed?
Gangue is sometimes reprocessed to extract any valuable minerals or metals that may be present in the waste material. By recovering these valuable resources, the overall efficiency of the mining operation can be improved, reducing waste and increasing revenue. Reprocessing gangue also helps in reducing environmental impact by minimizing the amount of material that needs to be disposed of.
What is the name of a process by which low-grade ore is separated from gangue?
refining
Why is the froth flotation method selected for the concentration of sulphide ores?
This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the water. The sulphide ores preferably wetted by the oil and the gangue with the water. Hence this method is suitable for the concentration of the sulphide ore
