[0002] It is the most common and effective method to recover gold elements from ore or other gold-containing materials using hydrometallurgical technology. In hydrometallurgy, gold is converted from solid phase to liquid phase under the action of leaching agent. Solid-liquid separation is performed on the leached ore slurry. The gold-containing solution is called noble liquid, and the solid phase is called leaching residue. In theory, the sum of gold content in noble liquid and tailings is equal to the gold content in raw ore. The percentage of the ratio of gold content in noble liquid to gold content in raw ore is the leaching rate. The determination of gold content in noble liquid is a key link for optimizing process conditions. In the prior art, a sampling tube is usually inserted into the noble liquid pipeline for sampling. However, this structure of sampling has the following technical problems: the noble liquid in the noble liquid pipeline comes from a high-level noble liquid storage tank. The pressure of the noble liquid pipeline is high. The sampling tube located in the pipeline is subjected to long-term erosion of gold particles in the high-pressure noble liquid, resulting in rapid wear of the sampling tube and low service life. Therefore, there is an urgent need for improvement. SUMMARY
