The Turtle Tough pH Sensor for Copper is not a one size fits all approach. Arguably our most application specific sensor we tailor it to meet the requirements of each individual installation. Unnecessary resistance elements can compromise both price and performance, so for this tough application we only put in what you absolutely need.
Copper ores are typically concentrated by either froth flotation or hydrometallurgical extraction, both of which have unique process challenges. Froth flotation is wrought with measurement difficulties; surfactants will coat measurement elements and report incorrect results where xanthates will continuously attack probe bodies and measurement elements, rendering sensors unusable very quickly. Copper oxide ores are typically leached with sulphuric acid and subsequently refined further via solvent extraction, with acids, sulphides and solvents all aggressively attacking all elements of the sensor.
The standard sensor is supplied with high levels of chemical resistance, including sulphide and dissolved gas resistance. Optionally, if the application requires we use solvent resistant sealants and different body plastics depending on the solids content of the ores. With this often tough application we are continuously evaluating each installation to ensure we supply the most robust and accurate sensor for copper ore processes. We are proud to say that our performance in this application has been unmatched anywhere in the world.
