Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms
An arrastra, also known as a Mexican Rastra, was a primitive method used by early miners to process gold and silver ores. It was introduced to the new world by the Spanish in the 1500’s. They were used throughout the world, often at remote locations where other processing methods were not feasible.
The mining industry consumes 2%-3% of the world’s energy. That’s the same amount of energy used by the entire airline industry. Our sensor-based sorters can reduce that energy consumption by 15%, as well as reduce the amount of water used by three to four cubic meters per ton of ore.
