Abstract: A method for mining soluble minerals from a subterranean deposit that comprises injecting a mining solvent into an injection wellbore passing through or contacting the deposit, wherein a heating means is allowed to heat the mining solvent while downhole and inside the wellbore thereby increasing the solvent temperature and reducing solvent heat loss is provided. The heated solvent is allowed to dissolve some of the soluble minerals from the deposit forming a mineral solution which is produced to surface.

Abstract: Methods for mining soluble minerals from a subterranean deposit. A fluid is injected into a horizontal injection wellbore passing through the deposit and allowed to enter a mining/fracture plane having at least one fracture, extending from the horizontal injection wellbore, at a pressure sufficient to further fracture the deposit, maintain the mining/fracture plane or open the mining/fracture plane. The injected fluid is allowed to dissolve some of the soluble minerals from the deposit thereby forming a mineral solution which is produced from horizontal production wellbores that intersect the mining/fracture plane.
