  • Patent number: 10508528
    Abstract: A method for in situ solution mining of a mineral from an underground evaporite stratum using a set of wells in fluid communication with at least one mineral cavity with some wells operated in solvent injection mode and other wells operated in brine production mode and optionally with some inactive wells, comprising switching the operation mode of one or more wells. The evaporite mineral preferably comprises trona. The at least one cavity may be formed by directionally drilled uncased boreholes or by lithological displacement of the evaporite stratum at a weak interface with an underlying insoluble stratum by application of a lifting hydraulic pressure to create an interfacial gap. The extracted brine can be processed to make valuable products such as soda ash and/or any derivatives thereof.

  • Publication number: 20170167239
    Abstract: In-situ solution mining method of an ore bed, particularly containing trona, which comprises exposing to a solvent an ore region inside a borehole drilled in the ore, and dissolving a desired solute within the exposed region to provide a liquor and create a voided ‘undercut’, such undercutting making the ore susceptible to gravitational loading and crushing. Unexposed ore falls into the undercut by gravity without breaking the ore roof resulting in exposure of fresh ore to the solvent and in preventing solvent exposure to contaminating material near the roof. The desired solute is eventually dissolved away in the entire bed from its floor up to its roof. Solvent injection may be delivered through a conduit positioned inside the borehole, and may be moved by retracting or perforating the conduit. The method may employ an advancing undercut initiated up-dip and traveling down-dip, or a retreating undercut initiated down-dip and traveling up-dip.

  • Patent number: 9638017
    Abstract: Batch initiation and/or exploitation phases of in situ solution mining of a mineral from an underground evaporite mineral stratum. The initiation phase may comprise a lifting step which employs a lithological displacement (lifting) of this stratum from an underlying non-evaporite stratum with application at the strata interface of a lifting hydraulic pressure greater than overburden pressure by a solvent suitable to dissolve the mineral; a soaking step for dissolution of mineral upon contact with stationary solvent, and a brine extraction step. The method may further comprise one or more exploitation phases carried out after the initiation phase. The exploitation phase may comprise a partial filing or filling step with the same solvent or different solvent than during lifting, another soaking step, and another brine extraction step. The lifting, cavity partial filing/filling, and brine extraction steps are being discontinuous. The evaporite mineral stratum preferably comprises trona.

  • Publication number: 20160356140
    Abstract: A lithological displacement of an underground evaporite mineral stratum from an underlying non-evaporite stratum comprising the application of a lifting hydraulic pressure of a fluid at a weak interface between the strata, resulting in lifting the overburden above the interface, separating the evaporite stratum from the underlying non-evaporite stratum and thus forming a mineral free-surface. The lifting hydraulic pressure is greater than the overburden pressure. The formed mineral free-surface is accessible for dissolution by a solvent. The fluid used for lifting may comprise a solvent suitable to dissolve the mineral. The evaporite mineral stratum preferably comprises trona, nahcolite, wegscheiderite, or combinations thereof.

The at least one cavity is preferably formed by lithological displacement of the evaporite stratum at a weak interface with an underlying insoluble stratum by application of a lifting hydraulic pressure. The extracted brine can be processed to make valuable products such as soda ash and/or any derivatives thereof, rock salt, or potash. This method can provide more uniform dissolution of mineral in the cavity, can minimize flow channeling, can minimize sodium bicarbonate blinding for solution mining of incongruent trona ore, and/or may avoid uneven deposit of insolubles.

  • Patent number: 9422166
    Abstract: In a process to produce sodium carbonate, a first production solution comprising sodium carbonate is introduced into less basic compartments of an electrodialyzer comprising alternating less basic and more basic adjacent compartments separated from each other by cationic membranes, the more basic compartments being delimited by anionic faces of bipolar membranes on one side and by the cationic membranes on the other side; a second production solution comprising sodium carbonate is introduced into the more basic compartments of the electrodialyzer; a solution comprising sodium hydroxide is produced into the more basic compartments by combination of sodium ions flux sodium ions crossing the cationic membrane and hydroxyl ions flux crossing the anionic face of the bipolar membranes, and is then extracted from the electrodialyzer to be used as a reaction solution; and the reaction solution is reacted with sodium bicarbonate in order to form a produced solution comprising sodium carbonate.
