Using particle-based separation models to evaluate the selectivity of different collectors in chalcopyrite flotation

Autor: Pereira, L., Schach, E., Frenzel, M., Tolosana Delgado, R., Rudolph, M., Gutzmer, J.

Publikováno v: Copper International Conference 2022, 13.-17.11.2022, Santiago, ChileVolume 10: Geometallurgy

Particle-based separation models are a powerful tool for modelling and understanding mineral separation processes at the level of single particles. Latest developments in this field have enabled the incorporation of complete particle datasets from im

An open source platform for predictive geometallurgy

Autor: Tolosana Delgado, R., Schach, E., Kupka, N., Buchmann, M., Bachmann, K., Frenzel, M., Pereira, L., Rudolph, M., Boogaart, K. G.

Publikováno v: IMPC 2020, 18.-22.10.2020, Cape Town, South Africa

Geometallurgy (the science of predicting the behaviour of ores along the value chain on the basis of their geoscientific characteristics) has barely moved beyond process mineralogy studies. These studies typically describe the mineralogical and micro

Interactive effect of particle size, liberation and hydrophobicity on the flotation kinetics of a carbonaceous phosphate deposit

Autor: Hoang, D. H., Schach, E., Hassanzadehmahaleh, A., Kupka, N., Pereira, L., Rudolph, M.

Publikováno v: Procemin-Geomet 2019, 20.-22.11.2019, Santiago, ChileProcemin-Geomet 2019

Selective separation of apatite from the associated minerals (quartz, calcite and dolomite) in a carbonaceous phosphate ore type strongly depends on the interactive effect of particle size, hydrophobicity and mineral liberation degree (LD). This stud

Investigation on the working mechanism of the nitrile based sulfide collector Tecflote

Autor: Schach, E., Lewis, A., Rudolph, M.

Publikováno v: Flotation '19, 11.-14.11.2019, Kapstadt, Südafrika

Tecflote is a new group of nitrile-based collectors for sulphide flotation. The fact that it is insoluble in water results in some interesting implications for its actual working mechanism. It can be assumed that the Tecflote-molecules are adsorbed i

Publikováno v: Procemin Geomet, 20.-22.11.2019, Santiago, Chile

For a long time, the mining and minerals processing communities have developed process models based on the bulk chemical compositions of ores and processing products. Recently, the emergence of the geometallurgy field and the advent of new characteri
