Challenge:  When metal prices rise, it becomes economically feasible for you to leach low-grade ores or dumps.  However, high pressure or high temperature leaching -- along with caustic conditions -- requires additional safety precautions. Corrosion is another serious issue affecting the selection of materials that come in contact with process flows. You need continuous, accurate measurements to prevent spills, regulate air and fluid flows, minimize the use of expensive reagents, and maintain tight pH control. You also need reduced resident time to minimize energy consumption and overall operating costs – and only a highly efficiency process can control cyanide and heavy metals.

Solution:  Emerson’s analytical instruments can help you ensure safe and efficient ore processing and tight pH control for maximum yield. The accuracy and reliability of Rosemount smart field devices give you the data needed to maintain the right process conditions to reduce reagent consumption, control energy usage, and operate safely.  They are essential to prevent emergencies like cyanide leaks that could have disastrous environmental consequences. Your high temperature and pressure autoclave applications will also benefit from the use of smart instruments with safety designations. And with field-generated diagnostics to support predictive maintenance of essential production assets, your operators will know when critical equipment needs repair or replacement. The end result?  You’re able to increase your plant’s reliability, maximize throughput/yield, and extract more value from the process. .
