  • Publication number: 20250249465
    Abstract: There is disclosed a method and apparatus for improving lithium yield of lithium lithium-selective media in one or more packed-bed columns in a direct lithium extraction process. The method comprises the steps of a) passing the lithium-selective media and a stream of process fluid through a screening zone; and b) collecting a portion of lithium-selective media having a required particle-size distribution and/or free of contaminants.

  • Publication number: 20250250653
    Abstract: There is disclosed a method for treatment of an aqueous lithium salt-containing solution in a direct lithium extraction process comprising lithium-selective media, wherein the aqueous lithium salt-containing solution comprises one or more foulants, the method comprising the steps of adjusting the oxidative-reductive potential and/or pH of the aqueous lithium salt-containing solution to render the one or more foulants inert to the lithium-selective media; and removing the one or more inert foulants from the aqueous lithium salt-containing solution prior to addition of the aqueous lithium salt-containing solution to the lithium-selective media in a direct lithium extraction process.

  • Publication number: 20240391787
    Abstract: There is disclosed a process for selectively purifying a lithium chloride product stream from an aqueous lithium salt-containing solution, the process comprising the steps of: introducing the aqueous lithium salt-containing solution to one or more columns filled with a lithium selective sorbent; flowing the aqueous lithium salt-containing solution through the one or more columns to adsorb lithium chloride from the aqueous lithium salt-containing solution onto a sorbent and form a sorbent with a greater lithium chloride content than the sorbent prior to introducing the solution; flowing a desorbent fluid once-through the at least one or more columns to desorb lithium chloride from the sorbent into an eluate stream, wherein the desorbent fluid is flowed in a co-current direction with respect to the direction of flow of the aqueous lithium salt-containing solution, and recovering a lithium chloride product stream from the eluate stream, wherein the eluate stream has a Li:TDS ratio of 0.08 or more.

  • Publication number: 20240279771
    Abstract: The disclosed process relates to a process for selectively purifying a lithium product stream from an aqueous lithium salt-containing solution in a continuous mode, said process comprising the steps of: a) introducing said aqueous lithium salt-containing solution to an arrangement of three or more packed-bed columns in series each filled with a lithium selective sorbent, wherein at least two of said three or more columns are at an adsorption stage, with one at a leading lithium chloride adsorption stage and one or more at a trailing lithium chloride adsorption stage, and at least one of said three or more columns is simultaneously at a lithium chloride desorption stage; b) flowing said aqueous lithium salt-containing solution through said at least two of said three or more columns at a leading lithium chloride adsorption stage and a trailing lithium chloride adsorption stage to adsorb lithium chloride from the aqueous lithium salt-containing solution and respectively form a fully-saturated sorbent and a parti

  • Publication number: 20060183607
    Abstract: A weightlifting apparatus includes a pair of spaced-apart support columns which carry a pair of spaced-apart self-spotter bars. The self-spotter bars extend from the columns such that the height and optionally the angle can be adjusted. The self-spotter bars are positioned to hold a weight bar at a safe height should the user drop the weight during an exercise.

  • Publication number: 20060012234
    Abstract: The invention is a support apparatus for a child's safety seat. The support apparatus allows the user to adjust the tilt of a child safety seat while maintaining a child in a safe position. The support apparatus comprises a base portion, an upper portion connected to one end of the base portion, and a bottom portion connected to an opposite end of the base portion. The upper and bottom portions may be attached to the base by adjustable hinges, or they may be attached in a fixed position. A foot support is attached to the bottom portion. The bottom portion engages the floor of a vehicle for added support. A child safety seat adapted to receive the invention is also disclosed.
