Safe operation procedure for electrowinning copper outfit in mineral processing plant

     1 Scope

This regulation stipulates the safe operation contents and requirements for the position of the copper-clad outfit.

This procedure is applicable to the electro-storage work in the wet smelting workshop.

2 content

1. Before you go to work, you must wear protective helmets, overalls, protective shoes, protective gloves, protective glasses and other labor insurance products.

2. Power off and power on according to the power failure and power-on operation procedures. Then go to the site to confirm that the short circuiter is indeed in a power outage

3. Outfit operation:

3.1 Output copper: When the vehicle is used to lift the copper, if there is broken copper, use copper wire to pass through the ferrule hole of the copper to tie the copper and the conductive rod together to prevent the copper. Drop into the slot.

3.2 Dropped into the tank should be promptly removed, and the electrolyzed copper with serious burning of the board should also be picked out in time and placed at the designated place.

3.3 Whole tank: The conductive plate between the tanks is polished, clean the conductive objects on the conductive board (such as copper particles, copper sulfate), and wash the conductive plates and contact points with hot water. If the anode moves when lifting the copper, the anode must be flushed.

3.4 Mounting the cathode: The crane shall be attached to the cathode above the sump. The operator shall level the cathode plate and the corner and pick out the unqualified ones. Then the crane will vertically position the cathode into the slot and To prevent the corners from being touched.

3.5 Whole tank: 撬 导电 conductive end conductive rod, adjust the cathode at both ends to make the board surface symmetrical with the anode, and then use the “pull line method” to adjust the cathode of the whole tank to the tidy ears and the pole pitch is uniform. The level plate is referred to a high level.

3.6 After the whole set of cathodes are installed, flush the water thoroughly, cover the trough cover cloth, and do not move freely on the trough.

3.7 After the operation, “3S” activities will be carried out around and under the trough. Hand over with the ESC position.

3.8 The copper copper removed from the tank is rinsed through the washing tank. Pay special attention to the ear washing. After washing, it should be rinsed in the washing tank. Washing and washing according to the process specifications.

3.9 After the bubble is washed, put it in the copper outlet and clean the PP ball entrained in the ear. After the appearance quality inspection, package it and touch the specified mark. Packing requirements are neat.

4 check: Check the tank under the same day and check if the breaker is good. Check the short-circuiting device of the trough group on the next day, and confirm whether it can work normally the next day.

5 slot surface short circuit inspection and processing operations:

5.1. Place the dragging table that detects the short circuit at the inner side of the highest point of the anode of the conductive end of the cathode conductive rod, and slowly shift the dragging table at a constant speed, and adopt the form of “dragging and touching”.

5.2. When the tow meter is walking, the place where the indicator light is on, that is, the short circuit detected, should be marked on the cathode conductive rod.

5.3, one pair of short circuit for processing, must deal with the short circuit: the curved surface must be flat. When lifting the cathode, be careful not to make the cathode hit the anode. After the treatment, the cathode conductive rod should be placed neatly, the lifting ears should be neat, and the pole distance should be uniform. After the inspection, the groove surface must be carefully flushed once and the main part of the rinse is at the contact point. After flushing, the hose is pulled down the grooved plate and the water valve is closed.

6. Strictly abide by the system of stopping the operation of water, steam, wind and electricity.
