Abstract
The invention provides a heavy magnetic suspension joint production method for recovering copper from copper smelting slag with high elemental copper content. The process flow comprises the following steps: feeding the copper smelting slag into a ball grinding mill, carrying out primary ore grinding; and feeding the copper smelting slag subjected to primary ore grinding into a grader, and carrying out primary grading and reselection. The process flow is characterized in that the sand setting obtained from the primary grinding and reselection is fed into a magnetic separator for magnetic separation, a copper concentrate I is obtained after the magnetic separation, and magnetic mineral after the magnetic separation is returned to the ball grinding mill; the overflow pulp of the primary grading and reselection is fed into a stirrer for mixing the pulp, and the mixed overflow pulp is fed into four groups of flotation machines for performing secondary roughing and secondary scavenging in turn; secondary ore grinding, secondary grading and secondary pulp mixing are matched, thus a copper concentrate II and a copper concentrate III can be obtained; and the tailings are discharged finally. The method provided by the invention can be used for solving the problems that the prior grinding flotation method is not suitable for recovering the copper smelting slag with high elemental copper content, the copper smelting slag is difficult to grind and the recovering index is poor; and the method is especially suitable for recovering metallic copper from the copper smelting slag with high elemental copper content.
Description
The ㈠ technical field: the present invention relates to non-ferrous metal and reclaim the process modification technology, especially a kind of heavy magnetic that reclaims copper from height contains the copper slag of bright copper floats combine production method.
The ㈡ background technology: valuable metal mineral such as copper can residually be arranged in the copper slag unavoidably, and the slag of modern copper metallurgy is usually with mill float glass process ore dressing recovery valuable metals such as copper wherein.Contained metallic copper in the general copper slag, great majority exist with the form of copper sulfide, only a few is elemental copper (being commonly called as bright copper) and cupric oxide, therefore, at present with the metallic copper in the beneficiating method recovery copper slag, generally all use mill float glass process (Fig. 1 is seen in technological process), can obtain good recovering effect, as mine tailing containing metal copper, be controlled at about 0.33%.
But the high copper slag that contains bright copper is with bessemerizing matte to produce blister copper, while output slag.The characteristics of this slag are the elemental copper (being commonly called as bright copper) that 30%-50% is arranged in the copper mineral.Because characteristics such as bright copper has the proportion height, and pliability is big are given with the ore dressing of mill float glass process and have been brought practical difficulty.Experiment shows, the difficult mill of slag, and index is very poor, can only be controlled at more than 0.9% as mine tailing containing metal copper, and metallic copper runs off serious, and can cause the not smooth of actual production technical process.
The ㈢ summary of the invention: purpose of the present invention is exactly will solve mill float glass process recovery technology commonly used can not adapt to the ore dressing recovery that height contains the copper slag of bright copper, the rate of recovery is very low, metallic copper runs off serious, problems such as production process is not smooth provide a kind of and contain the heavy magnetic that reclaims copper the copper slag of bright copper from height and float combine production method.
Concrete scheme of the present invention is: contain the heavy magnetic that reclaims copper the copper slag of bright copper from height and float combine production method, its technological process is: the copper slag that height is contained bright copper is sent into the 1st ball mill and is carried out ore grinding one time, send into the 1st grader again and carry out scalping and gravity treatment, it is characterized in that: scalping and gravity treatment gained sand setting are sent into magnetic separator and are carried out magnetic separation, obtain the copper concentrate I after the magnetic separation, the magnetic mineral after the magnetic separation returns the 1st ball mill; The overflow ore pulp of scalping and gravity treatment is sent into the 1st mixer and is once stirred and size mixing, send into the 1st group of flotation device again and carry out one roughing, can get the copper concentrate II, send into the 2nd grader through the mine tailing of one roughing and carry out the secondary classification, the secondary classification obtains sand setting and sends into the 2nd ball mill and carry out secondary grinding, return the 2nd grader again, the overflow ore pulp of secondary classification is sent into the 2nd mixer and is carried out secondary and stir and to size mixing, entering the 2nd group of flotation device again carries out secondary and roughly selects, can get the copper concentrate III, the mine tailing that secondary is roughly selected is sent into the 3rd group of flotation device and is carried out once purging selection, once purging selection gained concentrate returns the 2nd group of flotation device and roughly selects, the mine tailing of once purging selection is sent into the 4th group of flotation device and is carried out secondary and scan, and secondary is scanned the gained concentrate and returned the 2nd grader sorting, and mine tailing is scanned and discharged at last to secondary.
The present invention is on the basis that test of many times is explored, and found out one and has been fit to contain ore dressing the copper slag of bright copper from height and reclaims the heavy magnetic of metallic copper and float combine production method.Technology is reclaimed in the ore dressing of associatings such as the present invention adopts ball mill ore grinding, grader classification and double as gravity treatment, magnetic separator magnetic separation and multistage flotation device flotation, scans, secondary ball milling, secondary classification, the characteristics of technological process of the present invention are: through the grader classification, the classification overflow entered floatation system after slag was roughly ground through ball mill; Sand setting enters the magnetic separator magnetic separation, and magnetic separation bottom land product is as the part copper concentrate, and magnetic concentrate returns ball mill and regrinds.
Because the bright copper in the slag is more levigate than great and difficult, cause when carrying out the grader classification overwhelming majority's bright copper particle rapid subsidence become grader sand return and by enrichment, other ore of while is easier to levigate relatively and proportion is lighter, and great majority enter the classification overflow.Therefore, among the present invention grader when pressing gravity effect classification, the double effect of playing gravity separation.
Key component in the classification sand setting then enters the magnetic separator magnetic separation than great nonmagnetic and bright copper particle and vignite particle that particle is thicker, can easily obtain the copper concentrate than high-grade, and it contains copper grade and can reach more than 25%.
Owing to sorted out by magnetic separator in advance, therefore avoided among the present invention, so just saved power consume greatly in the grinding classification system multiple cycles than great difficult again levigate bright copper; Avoided a large amount of bright copper to enter into floatation system simultaneously and to cause the mine tailing copper grade to run high.
The present invention is by the floating combination method ore dressing of heavy magnetic, particularly reclaim in the technology and introduce magnetic separation process first in copper metallurgy, the metallic state copper that height is contained in the bright copper copper slag has obtained effective recovery, and mine tailing contains copper grade and is reduced to below 0.40%, is better than the mineral processing index that adopts general mill float glass process far away; In whole flow process, successively there are three places to receive copper concentrate simultaneously, effectively realized " early receive and overcharge ", reduced power consume.
