Improve the recovery rate of sulfur flotation concentrate

Its annual output of titanium concentrates 60,000 t. Sulfur-product cobalt concentrate O. B4 million t, the current production process for the flotation of a spiral re-election of a weak magnetic sweep the election a drying process continuous power choose a compact, a larger gap materials, the temperature is higher, in the delivery and sorting process of dust removal the problem has not been resolved. The main production facilities are often a result of the original dust removal system malfunction and failure. Process heat in dry fine-grained materials and equipment in operation at the point of falling easily distribute flying, resulting in job shop operating environment by pollution, indoor air dust concentration up to 20-60mg / m, much higher than the national health standard, the author Titanium electrostatic dust through the trials and tests, based on detailed analysis of the drying process dust electrostatic separation characteristics of the movement and distribution law, in order to explore a reliable technical solutions and the best dust model to select the best equipment, After design and construction of the transformation achieved remarkable social and economic benefits. First, the process and the original dust removal facilities 1. Titanium is the main process: the ferromagnetic end of ore, the Select a package concentrates power Selection process, the material from the kiln to start the dew, moisture content of less than 1, the temperature 150 ~ 200 ℃, warehousing, packaging until the concentrate is still 4O ℃ temperature around books are dry and hot like the delivery of materials and the sorting process . 2. Dry electrostatic separation process of the original dust removal facilities: In addition to electrostatic machine and packaging console equipped with two dust removal facilities, equipment and other processes (such as screening, tape transport, to enhance transportation, etc.) were not sealed and dust measures. The original design configuration of nine dust removal system, due to differences in selection and the actual production, but also for non-standard products. Difficult to maintain normal operation, a series of adverse effects of dust effect, that is fine mud surface area, absorption of pharmaceutical capacity, to a large number of pharmaceutical fine mud adsorption caused by the flotation recovery of coarse-down or drug consumption increases. Slurry viscosity can also fine-grained,######## oakley sunglasses, so that mineral particles and gangue flotation rate decreased mechanical mixture of strict firefly,air jordan high heels, so poor flotation, tests showed that the end is almost hard to fine. In view of this, the water should overflow cut off the flow of Sin to the mine in addition to flotation. -. Section 4 will be broken one thousand selected floor washing water diversion direct access into the flotation tailings launder site production, dry separation section in the floor of the wash water from the pipe into the ~ 500mm thickener concentration in the mine after the end of an integrated magnetic Young sent to the mine as a flotation 2O0.0 / / 11:1 × 2000ram mining equipment mixing tank, then gravity to JJF-20 flotation machine. Although it shares the concentration of low flow,ed hardy canada, but large volume of water,true religion outlet, and contains large chunks of varying size. With these large flows into the mixing tank and the flotation machine, they remain in the tank, such as the end of April 1990 shutdowns flotation washing machine, three flotation cells detected in about + + + a - ■ · ... · - ● a particle size of 30-70ram 10kg chunks. Therefore, stocks should reach the water on the flotation meaningless to the mine closure on the flotation, the flotation tailings to be diverted into the groove, it is best entered through filters to remove large 45m tailings thickener to reduce the stirred tank and flotation blocks, will help the process along the line of flotation. 5. Enhance flotation studies, taking into account the integrated iron and sulfur recovery plant to determine the optimal grinding selected fine through coarse grinding size on the flotation recovery of sulfur has been clearly demonstrated, processing plant expansion, the then the mill will increase, the first paragraph of grinding fineness may also further in the thick, coarse-grained magnetic tail in the flotation test work done even less, it should enhance this pilot study to explore the conditions for coarse grinding under the flotation time,replica oakley sunglasses, pharmacy systems, operating procedures and the corresponding production technology flotation index, taking into account the integrated iron and sulfur recovery plant to determine the best selection grinding fineness, the work to improve the sulfur recovery is essential.
