Definitions

  • the metallic cyanides precipitated by means of the proposed process that is theRECUPERATION OF CYA NIDES FROM RINSING SOLUTIONS OF CYANIDRIC PROCESSES FOR ELEC ⁇ TRODEPOSITION OF METALS, maybe directly re-used in the re ⁇ spective dips after their rinsing (the insoluble precipi ⁇ tate) in the filters or by deposition with water, until the rinsing water attains a density of 1.000 or 0° Be, thus re ⁇ leasing the precipitated cyanide fromthe other soluble ⁇ -x ⁇ p ⁇ nent
  • the same process presented may also be used for the precipi
  • the value of the reclaimed material is therefore 2.1 times the value of the metallic salt used for the recuperation.
  • the physical values are constant in ⁇ ternationally; -the values in money may show up in relation to the cost of the chemical products per country.
  • the copper, the zinc, the cadmium, the silver, the gold and cyanides are imported materials, thus justifying avoidance of the loss of these products in the rinsing solutions in the electroplating industry.
  • the electroplating industry is up against problems con ⁇ cerning the compliance with the standards of public organs, which are responsible for the preservation and protection of the ecology. They demand an efficient and complete treat ment of the industrial effluent waste products.
  • the precipitation formulation may be generalized consid ⁇ ering as -M- the symbol of a metal, the atomic weight of which is between 60 and 200, thus allowing the objective of the recuperation of the cyanides and the respective metals in the rinsing solutions.
