As part of Kappes, Cassiday & Associates' ongoing support for the minerals industry, KCA developed the LIFTERBOTTLE™ — a single-mold testing vessel with integrated lifters utilized for bottle roll leach studies. The bottle-roll leach test is one of the first tools an analytical chemist uses to determine the type and amount of leach reagents required for a given precious-metals ore.
Traditional bottle roll vessels rely on field-fabricated lifters glued or screwed into a plain bottle. Those fail and contaminate samples. The LIFTERBOTTLE™ is single-piece molded HDPE with integrated lifters — no field fabrication, no contamination, repeatable results across test runs.
United States Patent No. 9,187,211 B2 — "Milling Jar with Integrated Lifters" — issued 17 November 2015 to Kappes, Cassiday & Associates, Reno, Nevada (USA).
Standard for gold and silver cyanide bottle rolls — the most common analytical test in precious-metals metallurgy. Also used for: heap leach reagent screening; environmental leaching tests; oxidation studies; column leach pre-screening; cell & tissue agitation for biology research; mixing of suspensions in chemistry labs; aggregate and asphalt industries.
