The purpose of the test is to provide reasonable technical procedures and technical conditions for the mine through experimental research, to examine the economic feasibility, and to provide reference for the development and utilization of the mine.
During the test, due to the lack of detailed geological data and information on the nature of the ore, the iron ore mineral composition, mineral structure and construction of several iron minerals symbiotic relationship unknown to the test caused some difficulty, test personnel can only be learned through extensive testing The characteristics of the iron ore, after nearly half a month of experimental research, prove that the iron ore mineral composition is complex, it is a difficult to choose iron ore.
We conducted a variety of scheme comparison tests on the iron ore mine. 1. Weak magnetic separation yielded an iron concentrate grade of 63-64% with a recovery of 21%. 2. Weak magnetic-strong magnetic joint test: iron The concentrate grade can reach 55.37%, and the total iron recovery rate is 68.44%. The iron concentrate grade is 60%, the iron recovery rate 2, the weak magnetic-re-election joint test: the iron concentrate grade is 56.51%, and the total iron recovery rate is 56.88%. 3. Single re-election test: the iron concentrate grade is 55.60%, and the total iron recovery rate is 52.77%.
In order to improve the iron concentrate grade and total iron recovery rate, it is recommended to use magnetic roasting for weak magnetic tailings to make full use of mine resources and increase the economic benefits of enterprises.
All air duct installations for heating, cooling or ventilation are attached to mechanical equipment containing a fan or blower. Vibrations, noises and rattles resulting from the operation of the fan or blower are transmitted into the metal ducts which carry the noises throughout the system. In order to isolate the vibration and noises to the source, an air-tight flexible joint, consisting of a fabric which is secured to sheet metal on both sides, must be inserted between the equipment and the ductwork. This flexible joint is called a "Flexible Duct Connector." To meet every type of installation requirement, whether it be for factory, institution, office or home; Golmacool offers the widest variety of flexible duct connector fabrics (U.L. Classified) and sizes; preassembled with the sheet metal permanently secured to the fabric by means of exclusive seam locks. Golmacool Flexible Duct Connectors are dispensed from the carton, ready to complete fabrication faster, more efficiently, and more economically than any conventional method.
