LIQUID GUIDING AND COLLECTION PROCESS WITH SECONDARY CHANNELS FOR IN SITU LEACHING |
摘要 |
<p>An in situ leaching liquid collection process with secondary channels comprises:1) multiple liquid collection channels are provided in an ore body; 2) secondary channels are provided at both sides of the liquid collection channels, the main channel and secondary channels forming a multi-channel guiding and collecting control face for pregnant solution; 3) a sealing wall is arranged in the liquid collection channels, and the lower frontal part of the sealing wall is connected to the channel outlet by a conduit controlled by a ball valve at the outlet; 4) by alternately releasing and increasing pressure in the measurement and production process, a multi-channel pregnant solution collection system is formed at the liquid collection project control face; 5) by means of changing the loss ratio of non-mineral liquid and pregnant solution, the rare earth recycling rate is improved. The process favors the recycling of rare earth pregnant solution, and can reduce environment pollution.</p> |
