Scientificity of the principle of slurry electrolysis process
Traditional non-ferrous metal hydrometallurgy usually consists of three major processes: leaching, liquid-solid separation and solution purification, and electrowinning. Energy is consumed during mineral leaching, and the electrowinning process also consumes a lot of electricity. In particular, the energy consumption of the anode reaction in the electrowinning process is high, and the anode reaction process is not utilized, resulting in high energy consumption and complex processes for the entire process. Taking conventional copper electrowinning as an example, the anode potential of copper is 1.23V and the cell voltage is 2.1V. The energy required for the anode reaction in the copper electrowinning process accounts for more than half of the total power consumption, which is completely wasted. The anode gas precipitation overvoltage is high, and the produced oxygen is vented. If the power consumption of hydrometallurgy is 2400 kWh/ton of copper, then more than 1200 kWh is useless. The cell pressure of zinc electrowinning is generally around 3.3V, of which the anode potential is 1. 8V (including gas evolution overpotential), the anode reaction accounts for more than half of the total energy consumption, and metal sulfides need to undergo oxidation reaction during leaching. To complete the oxidation reaction, energy must be applied or a strong oxidant must be added. Therefore, from the overall perspective of hydrometallurgy, there is a very unreasonable phenomenon, that is, leaching generally requires external energy, while electrolysis wastes 1/2 to 2/3 of the energy. If the energy wasted in the electrolysis process can be used for leaching, it is very ideal from the overall perspective of hydrometallurgy. Combining the three processes of leaching, solid-liquid separation, and electrolysis into one, and directly producing metallic antimony from the ore pulp is a major breakthrough in the extraction of gold by hydrometallurgy.
Slurry electrolysis is a new hydrometallurgical technology developed in the past two decades. It combines the three processes of leaching, solid-liquid separation, solution purification, and electrolysis that are usually included in hydrometallurgy into one. It uses the anodic oxidation reaction of the electrolysis process to leach the ore. Its essence is to replace the anode reaction of the electrolysis process with the leaching reaction of the ore, so that the large amount of energy consumed by the anode reaction in the usual electrolysis process is converted into effective leaching of metals. At the same time, the cell voltage is reduced, the electrolysis power is reduced, and the entire process is greatly simplified. For traditional electrolysis or electrolysis, this is a major change. It not only greatly simplifies the process and has a high metal recovery rate, but also makes full use of energy, good environmental protection, and obvious economic benefits. Due to the different oxidation potentials of different metal sulfides and the different reduction potentials of different metal ions, the physicochemical properties of different metal compounds in a specific medium, such as solubility, also vary greatly. The existence of these differences makes slurry electrolysis able to achieve selective leaching of minerals and selective extraction of metal ions to a certain extent.
