PROCESSING LINE OF GOLD-SILVER ORE GRAVITY CONCENTRATION PRODUCTS Russian patent published in 1994 - IPC

FIELD: gold and silver ore processing. SUBSTANCE: processing line has two aggregates, mounted on movable platform and located in accordance with working sequence of process and connected to each other by transportation pipelines: aggregate for noble metals lixiviation and aggregate for extraction of noble metals from noble metals rich solutions. Processing line also has loading apparatus, that is placed in front of aggregate of noble metals lixiviation; apparatus to precipitate mercury from aurum-cyanic solutions, that is mounted behind aggregate for noble metals lixiviation; apparatus for extraction of noble metals from poor noble metals solutions, that is placed after apparatus to precipitate mercury; block of tanks-collectors for noble metals poor and rich solutions, that are located behind aggregate and apparatus for extraction of noble metals from noble metals solutions. Aggregate and apparatus for noble metals extraction from noble metals poor and rich solutions are connected by pipeline in one closed circuit with aggregate for noble metals lixiviation: first one - through tank-collector for rich noble metals solutions and apparatus to precipitate mercury and second one - through tank-collector for poor noble metals solutions. EFFECT: line is used to process gold-silver ore gravity concentration products. 9 cl, 11 dwg
