Measuring continuous level in autoclaves
Autoclaves are commonly used in the mining industry as a pre-treatment solution. For example, in ore plants a process called pressure oxidation is used for extracting metals (e.g. gold, copper, zinc, molybdenum, and uranium) out of refractory ores. This pre-treatment process takes place in large autoclaves.

About Us
An alternative to an autoclave is a roaster, a very high temperature oven that is often used instead of an autoclave if the ore to process contains a large amount of organic carbon. Roasting uses heat and air to burn the organic carbon into fuel and to burn the sulfur off ore, which we heat to 932 to 1,202 degrees F. Heap Leaching
