Technical Field
The utility model belongs to the technical field of hydrometallurgy, and particularly relates to a laterite nickel ore leaching liquid pretreatment mechanism, a laterite nickel ore leaching liquid neutralization treatment device and a laterite nickel ore leaching liquid neutralization treatment system.
Background
In the laterite-nickel ore wet smelting process, the leaching process mainly comprises a neutralization leaching reaction of metal oxide and sulfuric acid, and the leaching solution impurity removal and product neutralization process mainly comprises a neutralization reaction of metal ion hydrolysis into hydroxide, hydrolysis acid and neutralization of a neutralizing agent. The neutralization reaction process comprises the following steps: pre-neutralization, first-stage iron and aluminum removal, second-stage iron and aluminum removal, first-stage nickel and cobalt precipitation, second-stage nickel and cobalt precipitation, and neutralization and manganese precipitation. In the neutralization reaction process, a neutralizing agent is added to adjust the pH value of the leaching solution, so that the system reaches the hydrolysis pH value of the preset metal ions. The hydroxide precipitate generated by the hydrolysis of metal ions is subjected to solid-liquid separation to separate out impurity metals (or products).
The current production configuration scheme is that neutralization tanks of each neutralization reaction procedure are generally connected in series of 5 stages or 6 stages, so as to finely control the neutralization reaction time and the neutralization progress in stages. The neutralization tanks in series are arranged in a step manner, and the reacted liquid in the neutralization tank 1 automatically flows into the neutralization tank 2 through the chute and then flows to the neutralization tank in the last stage. In the actual production process, a neutralization tank is started to stir, leaching liquid from the upstream is pumped into a neutralization impurity removal first tank in the process through an upstream discharge pump, a neutralizing agent is added into the tank through a pipe orifice of a top cover of the neutralization tank, and the adding amount of the neutralizing agent in the stage is controlled by detecting the pH value of an overflow liquid outlet of the neutralization tank.
In the existing laterite-nickel ore wet smelting production process, the defects of the existing equipment and method in the neutralization reaction process are mainly that: firstly, the neutralizer is easy to cause blockage and scaling of pipelines and spray heads, so that neutralizer distributor equipment cannot be used in actual production; secondly, a mode of filling a neutralizing agent into a top pipeline is adopted, the neutralizing agent is mixed on the upper surface in the reaction tank, and the mixing is uneven; third, the reaction process produces a gas foam, causing the neutralizing agent to float on top of the foam, preventing rapid mixing of the neutralizing agent with the solution. All three conditions finally lead to local over-alkali in the neutralization reaction process of the neutralization tank, so that nickel cobalt metal is lost, and the product yield is reduced.
