Abstract: A method for separating and recovering bromine from circuit board incineration ash using a two-step process belonging to the field of comprehensive recovery of valuable elements from ash using full-wet processes. The method particularly relates to a method for efficient separation of bromine salts and separation and extraction of lead and zinc from circuit board incineration ash by using two alkali leaching processes. The method mainly comprises steps such as one sodium hydroxide alkali leaching process, two sodium peroxide alkali leaching processes, stepwise pH adjustment using industrial sulfuric acid, separation and extraction of lead and zinc, bromine salt evaporation and crystallization to recover crude bromine salt. Compared with the traditional ash comprehensive recovery process, the technology uses dissolution of bromine salts, lead and zinc by sodium hydroxide and strong oxidation in an alkali environment of sodium peroxide to oxidize and leach bromine-containing substances such as cuprous bromide, and realizes efficient leaching of bromide salt, lead and zinc by means of a two-step process, while enriching noble metals such as silver. This is advantageous for the subsequent recovery of noble metals, and the method has characteristics such as short process and no emission of tail liquid.

An in-phase input terminal of the error amplifier is applied with a reference voltage, an inverting input terminal thereof is connected to a first terminal of the first resistor, and an output terminal thereof is connected to a circuit to be connected. A first terminal of the capacitor is connected to the first terminal of the first resistor, a second terminal thereof is connected to the output terminal of the error amplifier, and a second terminal of the first resistor is connected to the control module. As the reference voltage is applied to the in-phase input terminal of the error amplifier and an adjustable control voltage is indirectly applied to the inverting input terminal thereof, the reference voltage is a ratio of a product of a variable control voltage and a secondary-side diode on-time to a power switch cycle, wherein the reference voltage is a fixed value, and so are the primary-side current detection resistance and the coil turns ratio, and therefore, the average output current of the circuit is constant.
