Embodiment 1
[0022] A kind of manganese carbonate pretreatment method, comprises the following steps:
[0023] (1) Put the manganese carbonate ore in a pulverizer to pulverize it, pass it through an 80-mesh sieve, take the bottom material, and place the bottom material in a microwave processor for 3 minutes, then mix the bottom material with nitric acid According to the mass ratio of 1:0.6, the stirring speed is 10r / min, and the temperature is adjusted to 35°C, stirred at a constant temperature for 10min, then placed in an ultrasonic processor, and ultrasonically treated for 10s to obtain a pulp;
[0024] (2) ore pulp is placed in reaction tank, and adds sodium hydroxide solution wherein, the sodium hydroxide solution, the mass percent of sodium hydroxide solution is 1%, and the sodium hydroxide add-on is 0.2 times weight of manganese carbonate ore, and then Put it at a temperature of 80°C, use ultrasonic treatment for 1min, then stir it with a stirring speed of 50r / min for desiliconizatio...
