The original patents for the flotation process were secured by C. V. Potter in 1901 and by G. D. Delprat in 1902. Controversy over the originality of each soon followed and litigation ensued, lasting until 1907. The Potter - Delprat process, as it was referred to after 1907, proved unsuccessful on a large scale.
