A process in which manganese is recovered from manganese nodules after the nodules have been treated to recover base metals such as copper, nickel, cobalt, and molybdenum. The process includes the steps of reacting the manganese in the nodules to yield a carbonate and subjecting the manganese carbonate to flotation. The manganese carbonate froth is collected from the top of a flotation cell ...

Standard froth flotation yields a concentrate of 7 – 9% nickel at a recovery of up to 70%. A higher nickel recovery from such low – grade feed stock would be desirable. To achieve these two methods were investigated and reported in the following: Non-oxidative leaching as an alternative to flotation…

In this flotation process, a nickel preconcentrate containing > 1.1% Ni was obtained from material containing as little as 0.36% nickel. An empirical relationship was developed to predict the ...
Jul 28, 2019· Sulfide ores can be separated using froth flotation and hydrometallurgical or magnetic processes to create nickel matte and nickel oxide. These intermediate products, which usually contain 40-70% nickel, are then further processed, often using the Sherritt-Gordon Process.
Nickel processing, preparation of the metal for use in various products.. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high melting point of 1,453 °C (2,647 °F) and a face-centred cubic crystal structure, which gives ...
result in nickel losses into the tailings. This problem can be overcome by using depressants like car-boxymethylcellulose (CMC) and guargum deriva-tives, although their cost accounts for as much as 60% of the reagent cost incurred in the plant. Developments in Flotation Flotation of Nickel Sulde Minerals
flotation favorable hydro-dynamics which produce higher active cell volumes, provide longer residence times and complement froth removal. Greater Availability Competing equipment cannot match the availability of our Dorr-Oliver, Eimco and Wemco flotation machines.

In this case, as a general rule because both copper and lead minerals tend to float well, these are usually the target bulk flotation minerals. Therefore the standard Cu-Pb-Zn flotation practice involves an initial flotation of a Cu-Pb bulk concentrate followed by two parallel circuit stages of copper-lead separation and separate zinc flotation ...
