  • Publication number: 20250003024
    Abstract: This disclosure discloses an extraction column for metal separation in an acid leaching solution of laterite nickel ore, and an extraction process thereof. The extraction column includes an extraction column tube body and a gas distribution device; an interior of the extraction column tube body is provided with an accommodating cavity for containing a continuous phase and a dispersed phase, the continuous phase and the dispersed phase are in countercurrent contact in the accommodating cavity; and the extraction column tube body is connected with the gas distribution device to make the gas distribution device pass gas into the accommodating cavity. The gas distribution device is used to control a pipe diameter of a gas outlet of the gas distribution device in a suitable range. Using turbulent effect of bubbles floating in a liquid phase, collisions and shears of the dispersed phase form dispersed phase droplets with suitable sizes.

  • Patent number: 11502344
    Abstract: A method for recycling lead from spent lead-acid battery paste, relating to the technical field of hydrometallurgy. In the method, firstly a reducing agent, and a lead paste are added into a zinc chloride solution for leaching in a stirring mill to cause lead in the lead paste to enter the solution, a lead cementation is performed by using zinc in the leached solution, after the lead cementation, the electrolytic zinc is produced by controlling an electrodeposition on the zinc chloride solution for a short time, the reducing agent is zinc, lead or hydrogen peroxide, a part of the electrolytic zinc is returned as the reducing agent for leaching, the step of returning the electrolytic zinc as the reducing agent can be omitted when the lead or the hydrogen peroxide is used as the reducing agent.

  • Patent number: 10518456
    Abstract: A method for preparing a PBAT laminated membrane composite material uses PBAT or a material with PBAT as the main component and other biodegradable plastic or superfine calcium carbonate in a mixture. The temperature of the mixture is increased by means of a lamination machine segment by segment, the material is heated slowly to a molten state, and the temperature of a rolling shaft is controlled by introducing cold water to the rolling shaft when the lamination machine conducts membrane lamination, so that the temperatures of rolling wheels and the laminated membrane are controlled.
