Embodiment 1
[0028] see Figure 1-Figure 6 , in the embodiment of the present invention, a sulfide ore heating oxidation experimental device is independently designed according to the experiment, and is composed of a constant temperature box 1, a temperature probe 2, a sulfur dioxide transmitter 4 and a paperless recorder 3.
[0029] The function of the constant temperature box 1 is to provide a medium-high temperature environment for the sulfide ore oxidation experiment, so as to accelerate the oxidation reaction of the ore, shorten the experimental period, and avoid the adverse effects caused by the long period of normal oxidation of the sulfide ore on the mine site; The hole penetrates the insulation layer to the working room inside the box so that the temperature probe 2 can go deep into it. The temperature probe 2 is a contact probe that measures the temperature by touching the object. There are four temperature probes 2 in this experiment, two of which are Measure the internal temper...
specific Embodiment
[0047] Specific embodiments are described as follows.
[0048] 1 Experimental scheme design
[0049] Experiments study when the ore pile reacts, specifically when it self-heats, when sulfur dioxide is produced, and the corresponding temperature. Because the experiments are different, the experimental designs are also quite different.
[0050] The simulation experiment of sulfide ore piles focuses on the self-heating, gas products and temperature changes of the ore piles, and the experimental samples come from the raw ore of the mine, so they can be grouped according to the actual sulfur content distribution of the mine. Since the sulfur content of mine sulfide ore is roughly distributed within 0-30%, and it is disorderly, it can only be classified according to the range, which is 0-10%, 10-20%, 20-30%. The simulation experiment is divided into three groups, and the experimental design is shown in Table 1.
