In 1866, the Prussian state converted all the mines in the Harz region into state ownership. In 1923 to Prussia Mining and Metallurgical Company. Several of Bad Gronde’s mines have now been merged into the Grond mine. In 1966 the mine output of about 270,000 tons, the total number of employees 830 people. In order to ensure profitability, the following measures have been taken: the addition of desilting and heavy medium sorting equipment to expand the plant selection capacity, the establishment of a new floor repair shop, the deepening of shafts, the adjustment of downhole layout and upgrading, the use of trackless loading and unloading equipment and a series of stopes in stopes Measures, the results of an annual output of nearly 450,000 tons of ore, the total number of employees reduced to 556, of which 476 were workers, staff 80 people.
