Embodiment 1

[0034] Step 1. First, power on the equipment, adjust the stirring device and the inflation device, and make sure that the equipment is in good working condition;

[0035] Step 2. With the stirring device and the aeration device closed, slowly add the mineral material to be leached, keep the particle size of the mineral material less than 20mm, and keep the adding height of the mineral material below the L-shaped rotatable drain pipe 9;

[0036] Step 3: After the mineral material is added, rotate the mouth of the L-shaped rotatable drain pipe 9 in the pool to the vertical upward position, and then start adding the sodium cyanide leaching solution prepared in advance. The amount of the leaching solution should be The ore is completely submerged, but no more than the upper port of the L-type rotatable drain pipe 9;

[0037] Step 4: After the ore 8 is fully infiltrated by the leaching solution, the stirring and aeration can be started, and the speed and aeration volume can be adju...

Abstract

The invention discloses a fast tank leaching test apparatus and an application method thereof. The fast tank leaching test apparatus comprises a tank body (4), a speed-variable stirring device arranged in the tank body (4), a gas-filling device connected to the speed-variable stirring device and arranged at the bottom of the tank body (4) and a draining device arranged on the wall of the tank body (4). Through low-speed stirring, the fast tank leaching test apparatus allows minerals in the tank to completely contact leaching agent; through enhanced gas filling, dissolution speed of gold is accelerated. According to the fast tank leaching test apparatus, the disadvantage that the test period of a traditional test apparatus is lengthy is overcome, and reference indexes for the leaching rates of heaping leaching and tank leaching of the minerals can be rapidly provided for mine enterprises. The fast tank leaching test apparatus is fast and convenient in parameter adjustment, reliable in operation, simple in structure, and convenient and safe to operate.

Description

technical field [0001] The invention relates to the field of pool immersion tests, in particular to a rapid pool immersion test device and a method for using the same. Background technique [0002] In the heap leaching process of low-grade gold ore, leaching test is often one of the preconditions. The purpose of the leaching test is to find out the process parameters such as the leaching rate and leaching time of the heap leaching ore before the large-scale heap leaching. Profit, as for the leaching time, the impact of a few days is not very big. [0003] Generally, the test before heap leaching is a column leaching test, that is, a plexiglass column with a diameter of 10-20 cm and a height of 1.5-2.0 m is loaded with ore samples to simulate heap leaching for a column leaching test. Since this test device simulates heap leaching, the ore cannot move inside the column, and the leaching speed must be slow; therefore, the leaching test generally takes 30-70 days. In today's...
