Heinrich Precht (born August 6, 1852 in Jübber , † June 18, 1924 in Hanover ) was a German chemist and mineralogist who dealt with the chemistry of potash salts .

Precht studied chemical engineering from 1872 at the Hanover Polytechnic and from 1875 to 1877 at the TH Berlin-Charlottenburg . During his studies he became a member of the Cimbria Hanover fraternity . In 1877 he received his doctorate in Göttingen and was then an assistant at the TH Hanover in 1877/78 before he went to the Neu-Staßfurt union , which promoted potash salts in Staßfurt . He became director in 1883 and was general director when he retired in 1917.

In 1903 he received the title of professor from the University of Berlin. In 1910 he was elected a member of the Leopoldina .

He introduced a quantitative determination of potassium with potassium hexachloroplatinate (IV) and in 1879 found a method to increase the potassium content in kainite . Under his direction, the mining of carnallite and langbeinite began in Staßfurt . He introduced soda production using the Solvay process in Germany. From 1882 he also investigated the pollution of the Elbe by wastewater from salt mining that was discharged into the Saale. As a mineralogist, he first described the mineral Douglasite . In 1908 he was elected a corresponding member of the Göttingen Academy of Sciences .
