Mineral processing is science and art of extracting metals and nonmetal from their ores, refining them and preparing them for use. Within extractive metallurgy, the major divisions in the order they may most commonly occur are, Mineral Processing (or Beneficiation),
In mineral processing, a number of unit operations are required to prepare and classify ores before the valuable constituents can be separated or concentrated and then forwarded on for use or further treatment. The field of mineral processing has also been given other titles such as mineral dressing, ore dressing, mineral extraction, mineral beneficiation, and mineral engineering. These terms are often used interchangeably.
Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals.
Department of Mines and Geology, under Ministry of Industry, Commerce and Supplies Government of Nepal has signed MOU with Southwestern Metallurgical Geological Testing Center under Sichuan Institute of Metallurgical Geology & Exploration (SIMGE) for mineral process and pilot test lab facilities for Dhaubadi Iron Ore.
1. MOU (dated 26 JUNE 2018) for Metallurgical and others different levels of testing of Iron ore was completed and final report are received as:
Result of Metallurgical test
1. As continuity of Metallurgical test for MoU for pilot test of hematite was signed on 17th June, 2019. The main objective of the MoU were:
About 5300 Kg hematite samples within 16 different places from Pokhari, Ramche and Dhaubadi blocks of Dhaubadi iron deposit, Nawalpur District in month of June, 2019.
Sample Packed
Crushed Sample in SMGTC
The analysis results indicate that, the Fe in the ore is the main recovery composition with content of 34.84%; the main impurity composition is SiO2 with content of 44.70%; the content of K2O, Na2O, P and S is respectively 0.012%, 0.013%, 0.034% and 0.003%.
Name | Weight | Product Rate | TFe Grade |
---|---|---|---|
Pokhari | 1549.00 | 30.98 | 34.65 |
Namche | 2516.00 | 50.32 | 32.36 |
Dhaubadi | 935.00 | 18.70 | 39.30 |
Total | 5000.00 | 100.00 | 34.37 |
The main objective of pilot test is get qualified concentrate from low TFe grade hematite ore. previous.
Jaw Crusher and roll crusher are used for grinding samples to the size of 3 mm which was completed.
