  • Both the cathode guides ( 2 ) as well as the anode guides ( 5 ) can be installed, optionally, with their corresponding cathode aligners ( 1 ) and anode aligners ( 4 ), which are fixed in a vertical position on both interior sides of the Nucleus.
  • the transversal profile of the cathode guide can be shaped like an omega, or a U and/or V, its length being greater than the length of the cathode immersed in the electrolyte, the width of the channel of the omega or of the U and/or of the V profile must be slightly greater than the thickness of the cathode in use.

  • the cathode guide can be reinforced with a shock absorber ( 3 ).
  • the transversal profile of the anode guide ( 5 ) corresponds to a channel whose distance between opposing faces must be slightly greater than the thickness of the anode that will be employed.
  • the aligners have the shape of a truncated cone or inverted truncated pyramid, open towards the center of the cell, and their function is to act as a funnel to facilitate the introduction of the cathodes and anodes respectively into the cell.
  • the cathode guides ( 1 ) may be used only with the anode guides ( 5 ), with or without aligners or the cathode guides only with a horizontal spacer module like the one in FIG. 04 , or the cathode guides together with the anode guides and the horizontal spacer module.
  • the installation in a Wet or in a Dry Cell can be executed by attaching elements to the Nucleus that make it easier to lift and transfer it with the help of the traveling crane of the EW plant. These elements can be located in positions occupied by cathodes, by anodes or at the ends of the Nucleus.
  • the version known as Cathode Type Nucleus Holder represented in FIG. 05 a - b consists of a bar ( 25 ) with two windows for the Crane hooks ( 23 ) and two coupling angles to be attached to the longitudinal support beam of the Upper Frame of the Nucleus ( 24 ). Two or more of these cathode type Nucleus holders attached in positions normally occupied by cathodes are needed.

  • the version known as Head-type Nucleus Holder, represented in FIG. 07 consists of one end that rests on the electrolytic cell upper head masonry ( 28 ) and one end that is attached to the Nucleus ( 29 ). These holding systems can be used independently one at a time or in any combination thereof.
  • these holders make it possible to lift, introduce and/or remove the Nucleus from the cell with all the cathodes and anodes in position, whether the cell is empty or full of electrolyte.
  • the Head Assembly Support Module consisting of four supports like the one shown in FIG. 07 may be installed. These supports are installed at the ends of the longitudinal support beams of the upper frame of the Nucleus ( 6 ) and ( 19 ), as shown in FIG. 09 , and their projecting head support ends of the masonry electrolytic cell ( 28 ) are located directly over the heads of the cell itself, preventing the lower frame of the Nucleus from resting on the bottom of the cell.
  • a module is being developed to facilitate the transversal circulation of the electrolyte.
  • the exemplary embodiments of the disclosed system is with such a module.
  • the Nucleus of the Modular System for Improving Electro-Metallurgical Processes similar to the one represented in FIG. 03 , was introduced into this cell.
  • the general dimensions of the Nucleus that was introduced into the Electrolytic Cell are 35 cm wide by 50 cm long and 35 cm high.
  • a module of five cathode guides ( 2 ) was coupled to each side on the left ( 6 ) and right ( 19 ) longitudinal support beams and on the lower right longitudinal support beam ( 11 ) and its lower equivalent on the left side. All this with its corresponding cathode aligners ( 1 ).
  • a Horizontal Spacer similar to the one shown in FIG. 04 , was coupled at the bottom of the cell, with six pairs of anode housing ( 20 ) and five pairs of cathode housing ( 21 ). The distance between anodes as well as that between cathodes was fixed at 100 mm, the same one used in the simulated Industrial Plant.
  • the cell was filled with copper sulfate electrolyte, having a composition equivalent to that of the simulated Industrial Plant, and the deposit was started at a potential of 2.6 Volts between anode and cathode, employing a current density of 300 Amperes per square meter.
  • the operational improvements include multiple benefits that arise from the absence of jacketed cathodes, absence of short-circuits and the ease with which the cathodes deposited can be loosened from the stainless cathode substrates with the Modular System for Improving Electro-Metallurgical Processes. The most important of these are: greater availability of equipment, reduction of human resources and reduction of raw materials costs. First, the factors that affect the greater availability of equipment are: 100% detaching in peeling machine, reduction of stripping frequency, increased useful life of the cathode, the anode and the cell, and increased availability of the traveling crane.
  • the reduction of the Human Resources corresponds to the reduced supervision of short-circuits, manual detachment of plates and rectification of short-circuited cathodes.
  • the cost reduction associated to other supplies used in the EW process relates to the elimination of plastic borders, the elimination of cathode/anode spacers and the consumption reduction of chemical reagents.
