The formation of slime particles in the processes of crushing and grinding
of minerals is a factor that limits froth flotation. Minera de Orgiva S.L.
(Spain) produces slime sludge containing 41.05 F2Ca from the benefice of a
fluorite ore. Slimes have a very small particle diameter with very high specific
surface area making this material difficult to process by froth flotation
technique even when the law of the material is high. Furthermore, removing
this fraction of the mineral from the flotation process generates waste that
causes the appearance of slagheap that affect negatively the environment.
In order to make this byproduct salable in the metallurgical fluorspar market,
this research studies the influence of physical variables and pH in the flotation
process of fluorite slimes. Four variables were studied: aeration flow rate, time
of flotation, agitator speed and pH. In order to evaluate the influence of each
variable the results were adjusted to a polynomial mathematical model based
in the relation between the variables and the measured factors. Optimizing
the process 76.21% of fluorite law is achieved in a single rougher steep with
a metallurgical recovery of 70.57% using values of 0.8 m3/h air flow rate, 7
minutes of time flotation, 1100 rpm and pH 9.25
Biography
José Raúl Corpas is currently carrying out his PhD studies at
the University of Granada. He started his PhD studies in 2017,
obtained in 2018 a scholarship from the Spanish state with
which he gives a practical application to his studies at the
companyMinera de Orgiva S.L. He startedworking at the Orgiva
MiningCompany under the project: Mineral concentration under
physic and chemistry methods. He has published 3 papers
in the flied of chemical engineering and has participated in 3
international congresses being the last one XIV International
Congress of Energy and Mineral Resources, Seville from April
10 to 13, 2018.
