Tailings from the Calumet and Hecla mills were called stamp sands after the steam driven stamp milling process. After the copper had been recovered, they were disposed into Torch Lake. The sheer scale of the mills can be appreciated in this 1906 photo taken from the tailings in the lake. (Courtesy, Library of Congress)

A high-value treatment of high-calcium gold-copper tailings is proposed. • NH 4 Cl solution was used as a leaching agent to prepare spherical vaterite that can exist stably.. Nanoparticle aggregation and crystal growth are two mechanisms of high-purity spherical vaterite prepared by CO 2 bubbling carbonation.
