"liquid collection process with liquid guiding holes for in-situ leaching an ore body to extract rare earth elements"

A liquid collection process with liquid guiding holes for in-situ leaching an ore body to extract rare earth, characterized in that:

• 1) multiple liquid collection channels are provided in the ore body;
• 2) liquid guiding holes with a slope or gradient of 1-2° are arranged to near the bottom of the liquid collection channels, and are provided on both sides of the liquid collection channels, a multi-channel mother liquid drainage and collection engineering network at least includes the liquid collection channels and the liquid guiding holes;
• 3) a blocking wall is provided in the liquid collection channels, the lower part of the blocking wall is connected to a channel outlet by means of a conduit, and the conduit is controlled with a ball valve switch at the outlet;
• and
• 4) through changes of the pressure, a pressure gradient is formed between the above ore be and the below engineering network, a multi-channel mother liquid collection engineering system is finally formed.
