Abstract: A method and device for separating and recovering heavy metal ions through membrane-forming mineralization fixation, applicable in the domain of acid wastewater treatment containing heavy metal ions. The process involves mixing composite mineral particles with heavy metal acidic wastewater, then conducting a first hydration reaction under static conditions. This leads to adsorption, precipitation, and crystallization of heavy metal ions in the wastewater via a colloidal liquid membrane, resulting in particles coated with a mineralized membrane. These particles exhibit a gap between the mineralized membrane and their core. The next step is to separate these coated particles and recover them. The preparation of composite mineral particles involves mixing sodium carbonate/sodium silicate, bentonite, carbide slag, and water, followed by a second hydration reaction and subsequent granulation, aging, and dehydration condensation. The particle sizes of both bentonite and carbide slag are maintained at ≤74 m.

Abstract: An intelligent separation device has gas explosion, stirring, drying and negative pressure adsorption devices. The gas explosion device receives conveyed peanut materials with red coats to be removed, and the materials are subjected to gas explosion, so that the peanut kernels and the peanut red coats are preliminarily separated. The stirring device shifts the preliminarily separated peanut kernels and peanut red coats into the drying device. The drying device compresses and heating external air, transfers heat through hot air, and heats and dries the preliminarily separated peanut kernels and peanut red coats, so that the peanut red coats and the peanut kernels are fully separated. The negative pressure adsorption device collects the fully separated peanut kernels and red coats with different densities and masses in a negative pressure adsorption mode.
