Title: Process for treatment of residues from ferriferous zinc ores
IPC: C22B3/00
Filed: 1978-12-29
Abstract: The present invention relates to a process for treating residues from a primary leaching of ferriferous zinc ores by sulphuric acid, with a view to recover a leadbearing by-product, such process comprising a secondary leaching of said residues, by sulphuric acid, within several countercurrent stages, at a temperature comprised between 85 DEG and 100 DEG C., the solid residues of the successive stages being circulated from the first to the last stage, the residue of this last stage being the said lead bearing by-product, whereas the various solutions separated from the second to the last stage are each recycled within the leaching operation of the respectively foregoing stage, and the dual zinc and iron sulphates solution, as separated from the first stage, being the principal product of the treatment. The primary leaching consists essentially of the chemical attack of the zinc oxide of the ore (naturally oxidized ore or roasted sulphur-based ore) by sulphuric acid and yields, as product, the zinc sulphate solution, which after purification, is used for the electrowinning of the zinc contained, whereas the solid residue from this primary leaching, when ferriferous ores are involved, is subject to the above said secondary leaching, in order to recover separately its zinc as sulphate solution, its iron as a precipitate and its lead as final residue of lead sulphate.

Title: Delay detonator.
IPC: F42B3/16
Filed: 1982-04-26
Abstract: Improved uniformity of timing, and particularly reduced sensitivity of timing to minor variations in delay charge size, are achieved in delay detonators by placing a loose load of a flame-sensitive ignition composition between a pressed delay charge and an ignition assembly, e.g., a percussion primer, at the actuation end of the detonator. The loose ignition charge has a free surface and is adapted to be ignited in response to direct contact with flame emitted from the ignition of a charge in the ignition assembly. Preferably, the delay charge is pressed into a plastic carrier which, in a non-electric detonator, has an open end terminating between the walls of the detonator shell and a primer shell that closes the actuation end of the detonator, and the ignition charge is loosely loaded into a metal capsule seated against the delay charge.
