Abstract: A seed starting tray including at least one cell defining a space, the at least one cell including a rigid upper portion defining an opening of the least one cell, and a flexible lower portion defining a base of the at least one cell, the flexible lower portion being transitionable between a first position in which the space defines a first volume and a first height and a second position in which the space defines a second volume and a second height, the first volume being greater than the second volume and the first height being greater than the second height.

Abstract: The present invention discloses a new process for leaching sulfide minerals consisting of leaching crushed ore in a vat reactor, wherein the leaching solution is fed with an ORP value close to the upper limit suitable for leaching and the exiting leaching solution leaves the reactor with an ORP above the lower limit suitable for leaching the ore. The output leaching solution that leaves the leaching reactor goes through an iron oxidation stage outside the leaching reactor, with the iron oxidation producing soluble ferric sulfate that is mixed with a recirculated portion of the output leaching solution to increase its ORP up to a value close to the upper limit of the redox potential range that is suitable for the ore leaching.

Abstract: A pool cue includes a butt that has a butt sleeve and a groove. A shaft extends from the butt and includes a tip. A grip is positioned within the groove. The grip is formed of a generally soft, elastomeric material. The grip is positioned in the groove such that a smooth continuous surface is defined with an outer surface of the butt. The grip is constructed of a material that is elastic enough to roll or slide over the butt sleeve and into the groove during assembly.
