Application Case: In gold mining, cyanide leaching is used to extract gold from ore. The process involves dissolving gold from the ore by using a cyanide solution.
Valve Positioner Role: Valve positioners control the flow of cyanide solution into the leaching tanks, adjusting the flow to maintain the optimal concentration of cyanide during the leaching process. The precise control of the chemical flow ensures that the gold is extracted efficiently without using excess cyanide.
Example: In a gold mining operation, the valve positioner regulates the flow of cyanide solution, ensuring that the gold extraction process is carried out under ideal chemical conditions and that the cyanide concentration remains consistent.
Importance: Accurate valve control not only maximizes gold recovery but also minimizes environmental impact by reducing the amount of cyanide used, helping ensure the operation complies with environmental regulations.
