Abstract

The design and operation of the vibratory cementation device comprises a vessel containing iron-rich acid solutions of dissolved copper and scrap iron as a reactant, wherein said vessel, which is formed on the basis of polymers or plastic due to the corrosion resistance, is subjected to vibration in order to accelerate the chemical reaction of copper precipitation and the dissolving of the iron, permitting a process without the risks associated with the generation of hydrogen gas given that the container vessel is open at the top.

Description

VIBRATORY CEMATOR

Background of the invention. The invention called "vibrating cementor" refers to a machine or reactor designed to remove dissolved copper in acid solutions from leaching processes of oxidized and sulphured minerals of copper or other metal.

The main cause that led to the creation of this invention is the need for a cement design that optimizes both economic value and safety and operational availability with respect to the rotary cement developed to treat ferrous chloride solutions rich in copper chloride , where said solutions or liquids come from the process of descobrization of molybdenum concentrates with ferric chloride. Description of what is known in the art and in the art.

As stated in the previous paragraph, what is known is the "rotary cementizer" developed to treat copper chloride rich solutions with high ferrous and ferric chloride contents, protected design in Chile as a Utility Model, Registration Number 155 and application No. 200100495. The high aggressiveness and power to dissolve metals such as steels of all types of ferric and cupric chloride led to design in this patent, a cylinder constructed of fiberglass-based materials with polymers or various rubbers to make it rotate and thus give movement to the iron scrap allowing the release of copper dendrites and keep the surface of the iron free to continue the chemical reaction that dissolves the iron and metallizes the copper, according to;

CuCI ₂ + Fe -> FeCI ₂ + Cu ₀

Then, the invention of the "Vibrating Cementor" uses the movement of the iron scrap, but based on vibration, so as to release the copper dendrites formed and make them fall to the bottom of the container for later extraction next to the liquid already exhausted in dissolved copper

Brief description of the Figures.

For a better explanation of the invention called "vibrating cementer", a description will be made of a preferred embodiment in relation to the following figures, where:

i Figure N ° 1 shows a two-dimensional overview of the "vibrating cementing" equipment, showing the machine with the equipment required to operate industrially.

Figure N ° 2 shows a sectional view of the "vibrating cementor" equipment tank, with all its components.

Description of the invention

Referring to Figure 1, the invention "vibrating cementer" consists of a device whose main body is the pond or bucket (1) preferably constructed of plastic material, such as high density polyethylene because of its characteristic of being inert to the acid attack of chloride Cupric and ferric chloride and resistant to the impact of the iron scrap when it is loaded, the bucket (1) is fed with iron scrap (18) through the chute of load (17), through the pipeline the feed (11) the liquid or acid solution rich in copper ions is charged to the maximum operational level that is detected by the level sensor (9) that will stop the liquid feed by stopping the pump or sounding an alarm depending on whether the equipment is fully automated or partially, in the annexed side vessel (8) the level sensor (9) is located whose design allows to avoid being hit by the pieces of iron scrap. The bucket (1) is mounted on the bed (4) that hangs from the platform (6) of the structure (7) by means of springs (3), eccentric pulleys (5) will move with a motor vibrating the bucket (1), said vibration can be programmed continuously or at intervals every certain periods of time, in this way the iron scrap is moved and stirred to release the copper dendrites that have formed or are in formation, causing them to fall to the bottom of the bucket (1) to pass through the bottom grill (2) whose objective is to prevent some piece of iron from covering the discharge valve (10). The piolas or chains of security (12) allow to ensure the bucket (1) of a detachment or cut of some spring (3) To increase the kinetics during the process of precipitation of copper the liquid can be recirculated by extracting it from the discharge valve (10) and introducing it back to the equipment through the power line (11).

The agitation system by a vibratory method of the bucket (1) requires a simpler infrastructure than is necessary in a rotating system that contemplates a motor system in addition to the turning infrastructure, as a consequence the vibratory movement system results in more favorable costs than the rotary motion system. Referring to Figure 2, the bucket (1) is opened in its upper part, which allows the immediate evacuation of traces of hydrogen gas that can be generated by the reaction of free acid with the iron, instead in the systems Cementing with rotating cylinders generally require a gas extraction system to minimize or prevent the accumulation of hydrogen gas inside.

The bucket (1) is preferably designed in its upper part with a conical shape inverse to the lower one to make a breakwater effect on the upper edge, the conical shape of the lower part, under the connecting flange (16), helps to direct the precipitated copper towards the discharge of the valve (10).

The bucket (1) is covered internally in the wall on the flange (16) with upper belts (13) of preferred high density polyethylene material connected with tie down bolts (15) and under the flange (16) it is covered internally with belts lower (14) also of high density polyethylene preferred material but thicker to bear greater friction with the iron scrap.

The attached side vessel (8) communicates with the inside of the bucket (1) by its lower part in order to allow the entry of only liquid during loading, thus allowing to automate the equipment with the application of a level sensor (9 ) that will define the term of liquid charge when activated. Similarly, after knowing the average times required to deplete the dissolved copper, the discharge of the bucket (1) is automated with the automatic use of the valve (10).

Claims

A machine designed to be applied in copper cementing or precipitation operations with the necessary movement to speed up the reaction kinetics allows to release the copper dendrites formed and adhered to the iron surface, reagent applied as iron scrap, leaving its surface free and clean to continue dissolving the iron and precipitating in it the CHARACTERIZED copper, because movement by vibration occurs by means of eccentric pulleys (5) driven by a driving force and being attached to the bed (4) that hangs from the platform (6 ) by means of springs (3) where the bucket (1) when attached to the bed (4) is subjected to vibratory motion. The bucket (1) that acts as a container of the metallic iron mixture with the acidic liquid that contains the copper ions, will speed up the chemical reaction with the vibratory movement that can be applied continuously or in sequential intervals. The vibration itself will cause the metallic copper to fall and slide to the bottom of the bucket (1) which, due to its high density in relation to that of the liquid, will decant rapidly.

The copper cementation equipment is according to claim 1, CHARACTERIZED, because the vibrating cementor allows automatic operation of the liquid feed by operating the level sensor (9) that will be activated when detecting level of operation when filling attached side vessel ( 8) that communicates with the inside of the bucket (1) by its lower part, thus giving the signal of loading end and beginning of the vibration sequences.

The copper cementing equipment is according to claim 1, CHARACTERIZED, because the bucket (1) that acts as a container of the metal iron mixture with the acidic liquid containing the copper ions is opened at the top, allowing the permanent outdoor evacuation of the generated hydrogen gas.

The copper cementing equipment is according to claim 1, CHARACTERIZED, because the bucket (1) allows the liquid contained from the discharge of the valve (10) to the feed duct (11) to be recycled in order to speed up the reaction kinetics
