Silver Sulphide Leaching & Filtration Circuit Startup & Shutdown Procedures

Details of good silver sulphide leaching and filtration circuit operation and instructions for sequencing and preparing for startup.

The following items must be checked before the equipment in this EXAMPLE Argentite Leaching Circuit is started.

The leach tank agitators should be running. Check that the Argentite filter feed pump, drum filter, repulper and tailings sampling pump are available to start up. Ensure that shut-off valve in the air line to each leach tank is open. Ensure that the timer for the lime addition has power and that the shut-off valves in the appropriate lime lines are open. Check the level of cyanide solution in the cyanide day tank to ensure there is an adequate amount to start the Argentite Leach Circuit. Ensure there is an adequate supply of flocculant available and that the flocculant metering pump is available to operate.

Good Concentrator Safety Guidelines & Practices

mining-safety TOP 10 Safety Rules

The following guidelines are considered good industrial practice:

When any equipment or structure is dismantled in whole or in part, and subsequently re-assembled, it must be completely checked and found to be safe before it is started up. Whenever a person observes what appears to be an unsafe or harmful condition or act he should report it as soon as possible to his supervisor. No person should intentionally remove any safeguard provided for the protection of workers. Machinery and equipment must be operated only by authorized persons. Before any equipment or machinery is put into operation the person responsible for doing so must ensure that all safeguards are in place and functioning, and no one will be endangered by putting the equipment or machinery into operation. No one will be allowed work while affected by alcohol, drugs or other substances which may endanger his health or safety or that of any other person. No one must engage in any improper activity or behavior that might create or constitute a hazard to himself or any other worker. Improper activity or behavior includes “horseplay”, scuffing, fighting, practical jokes, unnecessary running or jumping, or similar conduct.
