Abstract
The present invention discloses the use of Rhodococcus opacus bacteria for bioflotation of minerals of the apatite-quartz system, by adsorption on their surface and subsequent changing of the zeta potential, making them hydrophobic, in addition to reducing the surface tension of water.
Claims14
ADSORBENT AGENT, wherein it is used for adsorption on the surface of the apatite-quartz system and comprises at least one bacterium selected from the group comprising species of the genus Rhodococcus.
BIOFLOTATION COMPOSITION, wherein it is used in an apatite-quartz system and comprises:
- a. at least one adsorbent agent comprising at least a bacterium selected from the group comprising the species of the genus Rhodococcus;
- and
- b. an acceptable carrier.
PROCESS FOR BIOFLOTATION OF THE APATITE-QUARTZ SYSTEM, wherein it comprises adding to an apatite-quartz system an adsorbent composition comprising at least one adsorbent agent comprising at least a bacterium selected from the group comprising the species of the genus Rhodococcus.
PROCESS FOR BIOFLOTATION OF THE APATITE-QUARTZ SYSTEM, according to the preceding claims, wherein the apatite mineral comprises the fluorapatite subgroup.
PROCESS FOR BIOFLOTATION OF THE APATITE-QUARTZ SYSTEM, according to the previous claims, wherein the time of flotation is about two minutes and the pH of flotation is acid.
