Copper Mining & Copper (Sulfate) Refining

Precise, real-time monitoring helps realize the full value of copper present in mined material

According to the U.S. Environmental Protection Agency, the amount of marketable copper produced comprises a tiny fraction of the original material mined. Typical copper concentration levels in ores range from 0.5 to 1.0 percent. Thus, several hundred metric tons of ore must be handled for each metric tone of copper metal. During processing, the ore is crushed and chemically leached with weak acids, which seep through the copper-bearing rocks to dissolve any copper present into the leaching liquid, which is further processed to extract valuable copper.

Given the enormous quantity of materials that must be processed to extract small amounts of copper, precision really matters when it comes to process measurement and control. The smallest deviation in copper-concentration measurements can quickly add up to significant losses in potential revenues. Similarly, accurate and reliable real-time chloride-contamination monitoring during copper sulfate refining is critical to ensure that your final product and operations always comply with contractual obligations and environmental regulations. Galvanic systems offer a compelling price-to-performance advantage, delivering benefits to your company image – and your bottom line.
