A system for separating hydrocarbons from a solid source including a primary separation tank including a first hydrocarbon removing device to remove hydrocarbons from a slurry of water and solids. Further, the system including a transfer device between the primary separation tank and a secondary separation tank, wherein the transfer device is configured to transfer solids from the slurry to the secondary separation tank. Further still, the system including a second hydrocarbon removal device, a fine particle separation device to remove remaining solids in the secondary separation tank, and a product collection tank to receive hydrocarbons removed from the primary and secondary separation tanks.

What is claimed is: 1. A method to separate hydrocarbons from a solid source comprising:mixing a tarred solid source with water to create a slurry of water, solids and hydrocarbons in a primary separation tank, wherein the water is heated prior to mixing with the tarred solid source;separating at least a portion of the hydrocarbons from the slurry in the primary separation tank by one of a group consisting of settling, floatation, mechanical agitation, water circulation, aeration, gravity separation, and counter-current decantation;removing at least a portion of the separated hydrocarbons from the slurry in the primary separation tank;transferring the remaining slurry into a secondary separation tank;separating fine solid particles from the slurry;removing additional hydrocarbons; andrecycling the water.
