Embodiment Construction
[0025] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0026] refer to figure 1 A method for pumping mother liquor through a small hole is shown, the method includes an equipment installation process and a pumping process, wherein the equipment installation process includes the following steps:
[0027] S11. Drilling, using a drilling device to drill a pumping well 6 on the mine 2, a pumping well 6 is drilled at a certain distance above the mine 2, and multiple pumping wells 6 can improve the efficiency of pumping the mother liquor. The depth of the well 6 is required to pass through the mine 2 and the mineral source layer 1 to reach the bedrock layer 7, and the diameter of each pump well 6 is greater than the diameter of the small water pump 8, and less than twice the diameter of the small water pump 8. For the convenience of aperture Restricted, its diameter is required to be no more than 100mm.
[0028] S12. Reverse ...

The invention discloses a method for pumping mother liquor through small holes. The method comprises an equipment mounting process and a pumping process. The equipment mounting process comprises the following steps of S11, perforating, wherein a perforating device is adopted for drilling pumping wells 6 in a mine 2; S12, reverse filtering, wherein a reverse filter screen 9 is mounted outside the wall of each pumping well 6; and S13, pump mounting, wherein a small water pump 8 is placed at the well bottom of each pumping well 6. The pumping process comprises the following steps of S21, pumpingof the first time, wherein power of the small water pumps 8 is turned on, and the mother liquor is pumped for the first time; S22, seepage, wherein after pumping of the first time is completed, the power of the small water pumps 8 is turned off, and operators wait for a certain time till the leaching liquor flows to the pumping wells 6 in a seepage manner; and S23, re-pumping, wherein the mother liquor permeating in the pumping wells 6 is re-pumped till all the mother liquor is pumped. The method has the beneficial effects that the diameters of the pumping wells 6 can change according to changes of the diameters of the small water pumps 8, and the diameters of drilled holes can be reduced easily; the total time of mining is shortened, and work efficiency is improved; and equipment is easyto mount and dismount.
Description
technical field [0001] The invention relates to a method for pumping mother liquor through small holes, more specifically, the present invention mainly relates to a method for pumping mother liquor through small holes. Background technique [0002] Rare earths are composed of 14 natural elements, as well as synthetic elements. The natural reserves exceed 150 million tons, and the exploitable reserves exceed 88 million tons. The rare earth market is a diversified market. It is not just a product, but 15 rare earth elements and yttrium, scandium and their various compounds ranging from chlorides with a purity of 46% to single rare earth oxides and rare earth metals with a purity of 99.9999%. Has a variety of uses. In addition to related compounds and mixtures, there are countless products. At present, the main rare earth producing areas in my country are southern Jiangxi and central Inner Mongolia, and southern Jiangxi and Jiangxi are ionic heavy rare earths. Ionic rare ear...
