Embodiment 1

[0031] Put the copper-clad steel or copper-clad iron waste into the copper-clad pool with a diameter of 3 meters and a height of 5 meters to a place of 4 meters by an electromagnetic chuck machine, and pump the carbonized ammonia water condensed by the condenser to 40 cm above the furnace charge. According to the amount of ammonia water and ammonia water The concentration is used to calculate the total amount of ammonia in the copper pool, and then the amount of ammonium bicarbonate required is calculated according to the amount of fertilizer / ammonia = 5 to 8 times;

[0032] Pour the required ammonium bicarbonate evenly into the copper pool, blow air into the pool from the bottom, and bubble evenly. After 3 to 4 hours, check whether there is copper on the waste, and turn off the air until there is no copper on the waste. valve;

[0033] Pump the feed liquid into the iron removal tank, take samples and analyze the iron content in the feed liquid, then add hydrogen peroxide acco...

Embodiment 2

[0041] The copper-clad steel or copper-clad iron scrap is loaded into the copper pool with a diameter of 3 meters and a height of 5 meters to a place of 4 meters by an electromagnetic chuck machine. Pump the carbonized ammonia water down from the condenser to 60 cm on the furnace charge, calculate the total amount of ammonia in the copper pool according to the amount of ammonia water and the concentration of ammonia water, and calculate the amount of ammonium bicarbonate required according to the amount of chemical fertilizer / ammonia = 5-8 times (weight ratio) ;

[0042] Pour the required ammonium bicarbonate evenly into the copper tank, blow air into the pool from the bottom, and bubble evenly. After 3-4 hours, check whether the waste still contains copper, and close the air valve when there is no copper in the waste;

[0043] Pump the feed liquid into the iron removal tank, take samples and analyze the iron content in the feed liquid, then add hydrogen peroxide according to ...

Embodiment 3

[0052] The copper-clad steel or copper-clad iron scrap is loaded into the copper pool with a diameter of 3 meters and a height of 5 meters to a place of 4 meters by an electromagnetic chuck machine. Pump the carbonized ammonia water that comes down from the condenser to 50 cm on the furnace charge, calculate the total amount of ammonia in the copper pool according to the amount of ammonia water and the concentration of ammonia water, and calculate the amount of ammonium bicarbonate required according to the amount of chemical fertilizer / ammonia = 5-8 times (weight ratio) ;

[0053] Pour the required ammonium bicarbonate evenly into the copper tank, blow air into the pool from the bottom, and bubble evenly. After 3-4 hours, check whether the waste still contains copper, and close the air valve when there is no copper in the waste;

[0054] Pump the feed liquid into the iron removal tank, take a sample to analyze the iron content in the feed liquid, then add hydrogen peroxide ac...

Abstract

The invention discloses a production process of active copper oxide. The process comprises the steps that: (1) copper-clad steel scrap is added into a copper-melting tank; (2) needed ammonium bicarbonate is added into the copper-melting tank, and air is blown into the copper-melting tank from the bottom; (3) material liquid in the copper-melting tank is pumped into an iron-removing tank; hydrogen peroxide is added into the tank according to that a ratio of hydrogen peroxide to iron is 2-3:1; and a reaction is carried out for 2h under a temperature controlled at 30-40 DEG C; (4) obtained reaction liquid is added into a frame filter press; (5) a stirrer of a reaction vessel is started, a steam valve is opened, and a steam pressure is controlled at 0.1-0.3MPa; (6) a reaction vessel bottom valve is opened; a centrifuge provided with a filtering cloth is added under a stirring condition; and a filtrate formed in the centrifuge and washing solution are delivered into the copper-melting tank; (7) a filter cake formed in the centrifuge is delivered into a dryer, and a temperature in the dryer is controlled at 85-115 DEG C; and (8) obtained dry material is added into an externally heated rotary kiln. The production process provided by the invention does not cause sewage discharging.

Description

technical field [0001] The invention relates to the technical field of active copper oxide, and more specifically, relates to an active copper oxide production process. Background technique [0002] The traditional copper plating process uses a soluble anode process, using phosphor bronze balls as the anode to supplement the copper source. However, in the electroplating process, due to the irregularity of the electronic components, the current density distribution is uneven, and finally the thickness is uneven. Therefore, the process has the characteristics of poor process stability and low efficiency. [0003] At present, the horizontal electroplating process has been adopted in the market. Since the anode is insoluble, the activated copper oxide is used instead of the phosphor copper ball as the copper source. This process requires the activated copper oxide to have high activity, that is, it can be dissolved in the electroplating solution within 30 seconds. At the same ...
