A process line comprising a combination of mobile and relocatable equipment units is provided at an oil sand mine site. The process line may comprise: a mobile shovel; a mobile bin and double roll crusher; a relocatable conveyor belt extending along the mine face; a relocatable slurry preparation assembly, such as a secondary crusher and jet pump; a pipeline; and a relocatable desanding circuit of separators. The process line conducts the following steps: mining the oil sand; crushing it to conveyable size; conveying it to a slurry preparation location; further crushing it to slurrying size and mixing it with heated water to produce a pumpable, aerated oil sand slurry; transporting and conditioning the slurry in the pipeline; desanding it to produce a product comprising bitumen and water and tailings; depositing tailings in a retention facility; and removing the product from the mine site in a pipeline.
