The Ramu Nickel Project
A lateritic nickel depositwas discovered at Kurumbukari, a site south of the Ramu River, in the early 1960s and was owned by a succession of interests before management of the project was secured by Highlands Gold in 1992. In 1997 Highlands Pacific was established as a new company to manage the Ramu Nickel project on behalf of Ramu Nickel Pty Ltd

A GAM was used to fit the factors, the metal ...
Recycling of ferronickel slag tailing in cementitious materials
The ferronickel slag tailings were physically activated by grinding in a ball mill for 2 h, 5 h, and 8 h, and the specific surface areas are 493.3 m 2 /kg, 530.7 m 2 /kg, and 721.2 m 2 /kg, correspondingly (abbreviated as AN, BN, and CN). And the particle size distributions of ferronickel slag powders with different grinding times are measured by the …

A review of circular economy strategies for mine tailings
Table 1 shows as a major example the summary of the metal contents of various tailings from some of the existing and historic metal mines in Finland. The tailings contain for example nickel, cobalt and zinc. The value of the metals in one single tailings waste pile reaches hundreds of millions of euros calculated from the concentrations and ...
Efficient utilization of nickel rich Chromite Ore
The initial characterization confirmed the presence of nickel (0.5–0.9% Ni) in the ore, which led to the interest in smelting the ore to obtain nickel in the metal. The smelting behaviour of the tailings is studied under the submerged arc furnace and blast furnace condition, under varying basicity .
