Description

METHOD FOR MANUFACTURING AN ELECTROLYTIC CELL FOR USE IN AN ELECTROLYSIS PROCESS AND ELECTROLYTIC CELL
Field of the invention
The invention relates to a method for manufacturing an electrolytic cell for corrosive electrolyte and for use in an electrolysis process such as for a process for electrowinning or electrorefining of metals as defined in the preamble of independent claim 1.
The invention also relates to an electrolytic cell for corrosive electrolyte and for use in an electrolysis process such as for a process for electrowinning or electrorefining of metals as defined in the preamble of independent claim 11.
Metal refers in this context for example but not limited to copper, nickel, zinc, lead, and silver.
By a container unit is in this context meant a container that is in the form of a separate unit having an inner space limited by a bottom, a first side wall extending from a first side edge of the bottom, a second side wall extending from a second side edge of the bottom, a first end wall extending from a first end edge of the bottom, and a second end wall extending from a second end edge of the bottom. A container unit of this type is for example presented in publication US 5,066,379.
Publication US 5,066,379 presents a container formed of polymer concrete in which minerals such as copper are purified in an electrolytic process. The container includes a bottom and end and side walls for containing a corrosive electrolyte, such as, a sulphuric or hydrochloric acid solution. An overflow box is integrally formed in a first formation extending vertically along one end wall of the cell and an overflow pipe is molded into the first formation and extends from the overflow box outwardly of the cell. A vertical covered inlet channel or cast-in pipe is provided at the opposite end of the container and extends from its upper to its lower end.
A problem with electrolytic cells is that they are expensive to manufacture and expensive to transport and install because of their large size.
Objective of the invention
The object of the invention is to provide an electrolytic cell that is economical to manufacture, transport and install.
Short description of the invention
The method of the invention is characterized by the definitions of independent claim 1. Preferred embodiments of the method are defined in the dependent claims 2 to 10.
The method comprises a step for providing a container unit having an inner space limited by a bottom, a first side wall extending from a first side edge of the bottom, a second side wall extending from a second side edge of the bottom, a first end wall extending from a first end edge of the bottom, and a second end wall extending from a second end edge of the bottom. The method comprises additionally a step for providing a support member designed and dimensioned to extend at least partly in the inner space of the container unit between the first end wall of the container unit and the second end wall of the container unit. The method comprises additionally a step for arranging the support member at least partly in the inner space of the container unit between the first end wall of the container unit and the second end wall of the container unit to divide the inner space of the container unit into a first part for a first row of anodes and cathodes in alternating order and into a second part for a second row of anodes and cathodes in alternating order.
The electrolytic cell of the invention is correspondingly characterized by the definitions of independent claim 11.
Preferred embodiments of the electrolytic cell are defined in the dependent claims 12 to
20.
The electrolytic cell comprises a container unit having an inner space limited by a bottom, a first side wall extending from a first side edge of the bottom, a second side wall extending from a second side edge of the bottom, a first end wall extending from a first end edge of the bottom, and a second end wall extending from a second end edge of the bottom. The electrolytic cell comprises a support member arranged at least partly in the inner space of the container unit between the first end wall of the container unit and the second end wall of the container unit to divide the inner space of the container unit into a first part for a first row of anodes and cathodes in alternating order and into a part for a second row of anodes and cathodes in alternating order.
The invention is based on providing a support member and dividing the inner space of the container unit into a first part for a first row of anodes and cathodes in alternating order and into a part for a second row of anodes and cathodes in alternating order. By doing so, the metal producing capacity is increased relative to the production, transport and installation costs of the electrolytic cell in comparison to an electrolytic cell according to the prior art. One reason for this is that if more anodes and cathodes producing capacity can fit into one container unit, the specific production cost of the container unit is reduced. In addition, the relative transportation and installation costs are lowered due to fewer transportation movements and fewer installation activities for the specified production capacity.
In a preferred embodiment the container unit has the following dimensions: The width of the container unit is between 2.5 and 2.6 m, the height of the container unit is between 1.7 and 1.8 m, and the length of the container unit is between 5.6 and 6.0 m.
