Embodiment 1
[0057] The resource processing method of the ferromolybdenum slag of the present embodiment, as figure 1 shown, including the following steps:
[0058] 1) Weigh 200g of ferromolybdenum slag into a 1000ml beaker, add 570ml of hydrochloric acid with a mass concentration of 10%, and 57ml of hydrogen peroxide with a mass concentration of 20%, heat to 50°C under stirring, and after leaching for 3 hours, cool to 30°C. Filtrate A and 191.2g of filter residue A were obtained by filtration, the primary wet filter residue A was processed in step 7), and the primary filtrate A was a yellow transparent solution, which was processed in step 2);
[0059] 2) Add the primary filtrate A obtained in step 1) into a 1000ml beaker, heat to 55-60°C under stirring, add solid sodium hydroxide until the system pH=1.0, and filter to obtain filtrate B and filter cake B. The filter cake B is Molybdic acid crude product, filter cake B is washed with water, filtered, and dried to obtain finished molybdic ...
Embodiment 2
[0067] The resource processing method of the ferromolybdenum slag of the present embodiment comprises the following steps:
[0068] 1) Weigh 200g of molybdenum ferromolybdenum slag into a beaker, add 400g of acidic oxidation leaching agent mixed by mass concentration of 10% hydrochloric acid and mass concentration of 32% nitric acid according to the volume ratio of 100:10, and heat to 50°C, after 5 hours of leaching reaction, cool to 30°C, filter to obtain filtrate A and 186g of filter residue A, once wet filter residue A enters step 7) for processing, and once for filtrate A enters step 2) for processing;
[0069] 2) Add the primary filtrate A obtained in step 1) into a beaker, heat to 40°C under stirring, add solid sodium hydroxide until the system pH=0.9, filter to obtain filtrate B and filter cake B, and the filter cake B is crude molybdic acid , the filter cake B is washed with water, filtered, and dried to obtain the finished molybdic acid, weighing 2.8g; the filtrate B ...
Embodiment 3
[0077] The resource processing method of the ferromolybdenum slag of the present embodiment comprises the following steps:
[0078] 1) Weigh 200g of ferromolybdenum slag into a beaker, add 1200g of acidic oxidation leaching agent mixed with 10% hydrochloric acid and 20% hydrogen peroxide at a volume ratio of 100:5, and heat to 95°C, after 3 hours of leaching reaction, cool to 30°C, filter to obtain filtrate A and filter residue A, once wet filter residue A enters step 7) for treatment, and once for filtrate A enters step 2) for treatment;
[0079] 2) Add the primary filtrate A obtained in step 1) into a beaker, heat to 90°C under stirring, add solid sodium hydroxide until the system pH=1.2, filter to obtain filtrate B and filter cake B, and the filter cake B is crude molybdic acid , the filter cake B is washed with water, filtered, and dried to obtain the finished molybdic acid, weighing 3.0g; the filtrate B enters step 3) for processing;
[0080] 3) Add the filtrate B obtain...
