Flotation oils, processes and uses thereof

A flotation oil comprising:

• an intermediate stream obtained from an upgrader, a refinery, a slop, or slurry tank of gasoil and/or heavier streams,
• wherein the flotation oil comprises at least one of the following properties:
• a density at 15° C., as measured by ASTM-D4052, of 0.87 g/ml to 1.2 g/ml;
• a flash point, as measured by ASTM D93, that is equal to or greater than 50° C.;
• and
• a resin content, as measured by SARA (Determination of Saturates, Aromatics, Resins, and Asphaltenes (SARA) as measured by IP-469), of 2 wt. % to 25 wt. %.

• a kinematic viscosity at 40° C., of 10 cSt to 1000 cSt;
• a flash point, as measured by ASTM D-92 that is greater than 50° C.;
• and
• a resin content, as measured by SARA (Determination of Saturates, Aromatics, Resins, and Asphaltenes (SARA) as measured by IP-469), of 0 wt. % to 25 wt. %.
