Problems solved by technology

Thickeners are commonly used thickeners, but traditional thickeners are large in size, large in floor space, and high in cost. Therefore, in terms of economic rationality, small and medium-sized mineral processing enterprises generally seldom use them.

Embodiment 1

[0021] The heavy particles in the tailings settle quickly, so that more than 90% of the minerals can settle in a short period of time, and only a small amount of fine minerals suspended in the inner water are not easy to settle, and it takes a long time to settle. This characteristic of the tailings makes it difficult to produce clean water that meets the standards, which is the main reason for the large volume and high cost of the thickening equipment. On the other hand, it is not difficult to produce high-concentration tailings. From this point of view, high-concentration tailings can be discharged to the tailings pond without clear water, which can save a lot of power for the mortar pump. Based on this principle, a power-saving and water-saving method for treating tailings was invented. The workflow is as follows:

[0022] This embodiment is a technical solution for saving electricity and water for tailings treatment, such as figure 1 As shown, in the method of the prese...

Embodiment 2

[0028] The low-concentration tailings containing fine suspended matter obtained in the present invention are directly recycled because they are inconvenient to be discharged to the tailings pond with a mortar pump (wasting electric energy of the water pump) and cannot be directly discharged on the spot (damaging the environment). In this way, the processing capacity of the mill will be affected, but because the mineral content in the recycled water is very small, the impact is not large and will not have a significant impact on the entire process. Specific data such as the tailings of a small-scale iron concentrator in this embodiment:

[0029] Tailings flow 120m 3 / h, concentration 15%, density 1100kg / m 3 , the height difference between the tailings pond and the factory area is 45m, and the loss along the way is 15m. The mortar pump is 40% efficient. The power of the matching mill is 240kW.

Abstract

The invention relates to an energy-saving control method for treating tailings. The energy-saving control method for treating tailings is characterized by comprising the following steps: concentrating tailings in a concentration basin, settling high-concentration tailings into the bottom, leading low-concentration tailings at the upper part into a low-concentration tailing basin through a connection pipeline, arranging a concentration detector at the upper part position at which the connection pipeline is arranged in the concentration basin, and arranging a valve on the connection pipeline; directly draining the high-concentration tailings to a tailing pond through a mortar pump; when the concentration detected by the concentration detector is higher than a certain threshold value, closing the valve, stopping the leading of the low-concentration tailings into the low-concentration tailing basin until the concentration achieves or is lower than the threshold value, opening the valve, and starting energy-saving and electricity-saving procedures; and mixing the low-concentration tailings in the low-concentration tailing basin with clear water through a clear water pump and delivering to a production area. The energy-saving and electricity-saving procedures not only can save great electricity of the mortar pump, but also can save the usage amount of clear water.

Description

technical field [0001] The invention belongs to the field of industrial energy saving, and in particular relates to an energy saving control method for processing tailings. Background technique [0002] At present, most of the tailings of small and medium-sized enterprises adopt the direct discharge method, which belongs to extensive production. Since the concentration of tailings in the concentrator is generally not high, if it is directly discharged to the tailings pond, it will consume a lot of power consumption of the mortar pump, and also A large amount of fresh water will be consumed. Therefore, it is necessary to concentrate the tailings. Thickeners are commonly used thickeners, but traditional thickeners are large in size, occupy a large area, and cost high, so they are generally seldom used in small and medium-sized beneficiation enterprises in terms of economic rationality. Contents of the invention [0003] Based on the problems existing in the prior art, the ...
