Abstract
The invention discloses a method for screening and separating a copper alloy from copper ore. The method sequentially comprises the following steps of: (1) crushing the copper ore, namely crushing the copper ore into particles with the diameter of 5 to 10cm by using a crusher; (2) heating, namely heating the copper ore which is crushed into the particles in a high temperature furnace at the temperature of between 400 and 500 DEG C until the copper ore is burnt red; (3) quickly melting, namely immediately pouring the burnt red copper ore into lime water, wherein the hot ore is cooled as soon as the hot ore contacts the water and is immediately melted into ore mud; and the ratio of lime to water is 20:100; and (4) washing and separating, wherein ore sand melted into the ore mud is thoroughly separated from metal; metal particles are not adhered to the ore and can be easily separated and screened; and copper alloy particles are deposited by washing with clear water for multiple times. Compared with traditional separating and screening, the method has the obvious advantages of large extracting quantity, simple refining procedure, high metal extracting rate, good comprehensive using effect and the like.
Description
Technical field
The present invention relates to a kind of screening and separating technology of ore, relate to a kind of triage techniques of copper mine stone.
Background technology
Copper is one of human copper alloy the earliest of finding, and its matter is soft, is rich in ductility, has good heat conduction and electric conductivity, beats the instrument that can be processed into and daily necessities a little.At present, China's copper mine stone screening technique is: become particle to ore with crusher in crushing earlier, use grinding machine the thin washing of graininess copper mine stone mill then, sludge is separated with copper alloy, at last copper alloy is extracted.According to the method, the copper alloy particle of each screening can only extract the copper alloy of 75%-80%, still has the copper alloy of 20%-25% to fail to propose; The copper alloy particle that filters out also contains a spot of ore mud in the inside, makes when refining, to add difficulty, when smelting, has slag and produces; In the ordinary course of things, all adopt steel ball in grinding machine that graininess copper mine stone mill is thin, general being difficult to is ground to certain fineness to ore; Simultaneously wear into dust to the copper alloy of a part of soft property; Can mix some iron powder copper alloys again in the inside in the mineral powder simultaneously, strengthen the smelting difficulty again, when refining copper, will produce slag.
Summary of the invention
The present invention is directed to top said defective, a kind of method of copper mine stone screening and separating copper alloy is provided, separation purity is approximately the method for 99% copper alloy.
The objective of the invention is to be achieved through following technical scheme.
The method of copper mine stone screening and separating copper alloy is characterized in that: may further comprise the steps successively.
(1) copper mine Shi Po is broken: using disintegrating machine that copper mine Shi Po is broken into diameter is 5 to 10 centimeters particle.
(2) heating: the copper mine stone that will be broken into particle is put into 400 to 500 degree high temperature furnaces and is heated, until copper mine stone burn till red as fire till.
(3) instantizing: will burn red copper mine stone and fall immediately in the limewash, burning hot ore one is cool from the speed to water, is melted into ore mud at once, the ratio 20:100 of lime and water.
(4) washing separates: the ore in sand form that is melted into mineral slurry separates with copper alloy, and copper alloy particles no longer and ore are stained with sticking, and separation screening passes through the clear water washing again, and what precipitate is the copper alloy particle.
The invention has the beneficial effects as follows: (1) copper alloy is not afraid of high temperature incineration, has stone material in the copper mine stone only by the high temperature incineration loose deliquescing that can become, copper alloy at high temperature extracted amount up to 99%; (2) the red copper mine stone of burning is poured in the water or is clarified in the limewash; Copper mine stone can fast thawing become mud; Copper alloy does not then reach better preservation and gets off, and can not mix other copper alloy and impurity at copper mine stone mill detail yet, has reduced the difficulty of copper smelting alloy once more.Method of the present invention is compared with traditional separation screening, and extracted amount is high, and the refinement operation is simple, and the copper alloy recovery rate is high, fully utilizes the effective remarkable advantage of Denging.

(4) washing separates: the ore in sand form that is melted into mineral slurry separates with copper alloy, and copper alloy particles no longer and ore are stained with sticking, and separation screening passes through the clear water washing again, and what precipitate is the copper alloy particle.
embodiment 2.
The method of copper mine stone screening and separating copper alloy is characterized in that: may further comprise the steps successively.
(1) using disintegrating machine that copper mine Shi Po is broken into diameter is 10 centimeters particle.
The copper mine stone that (2) will be broken into particle is put into 500 degree high temperature furnaces and is heated, and burns till red as fire until copper mine stone.
(3) will burn red copper mine stone and pour into immediately in the limewash, burning hot ore one is cool from the speed to water, is melted into ore mud at once, the ratio 20:100 of lime and water.
(4) washing separates: the ore in sand form that is melted into mineral slurry separates with copper alloy, and copper alloy particles no longer and ore are stained with sticking, and separation screening passes through the clear water washing again, and what precipitate is the copper alloy particle; Next refine by routine.
