Many metals ore-dressing technique adopts backwater before traditional factory or tailings storage backwater tapered method because the character recycling water utilization rate of its technology self will reach 75% is unusual difficulty.In the ore-dressing of polymetallic ore process, various valuable metals to be separated and become product separately, add inhibitor with regard to needs when just sorting a certain purpose metal other metal is suppressed, but when next step sorts other metal, just need the adding activator that the metal that has been suppressed is activated.The water Returning process that employing selects preceding backwater of true tailings factory of factory or mine tailing storehouse to return uses, and remaining activator will make ore-dressing technique the separation difficulty between the metal occur in the backwater, and this can bring two large problems:
1, metal loss.The metal that should be suppressed has entered in other metal product owing to being activated, and has caused the loss of this kind metal.
2, product is defective.The metal that is activated has entered in other product, has caused containing mutually surpassing the relevant product standard of country in the product, will can not produce qualified concentrate containing when serious.
The heavy metal wastewater thereby that produces for the ore dressing plant all is to adopt the method for handling total mine tailing at present, and the waste water of total mine tailing often contains multiple beneficiation reagent, and processing procedure is loaded down with trivial details, and medicament is difficult for eliminating, and this waste water recycling can have a strong impact on the ore dressing quality.Processing method has simple chemical method and physico-chemical process two big classes from the research aspect, but want and to be extensive use of industrial, necessary technology maturation, simple to operate and economically feasible, present the whole bag of tricks all has limitation, and because the waste water complicated component, processing cost can increase greatly.So the most employing in ore dressing plant simply natural sedimentation in the mine tailing storehouse, sunlight is exposed to the sun method processing back with regard to the Returning process use, consequently makes metal recovery rate lowly cause metal loss, the wasting of resources, can not produce qualified products in the time of seriously.
Summary of the invention
For overcoming the defective that recycling water utilization exists in the existing ore-dressing of polymetallic ore, improve the mineral processing index of recycling water utilization rate and concentrate, technical scheme of the present invention provides a kind of recycling water utilization method of ore-dressing of polymetallic ore, be that polymetallic ore adopts bulk flotation step by step, select the bulk concentrate of multiple metal successively, bulk concentrate carries out the concentrate that separating flotation obtains single metal again.The intermediate products that polymetallic ore bulk flotation is produced, concentrate and tailings are through processed, and the backwater of generation directly returns the flotation operation that is used for the single metal ore deposit.
Described polymetallic ore is the polymetallic ore that contains two or more metal, preferred copper-lead zinc molybdenum multi-metal ore deposit; Described processed is dense processed.
The recycling water utilization method of technical solution of the present invention is applicable to the ore-dressing technique of polymetallic ore, is particularly useful for the ore-dressing of polymetallic ore technology that flotation step by step obtains the single metal ore deposit.Detailed process is an example with the ore dressing of copper-lead zinc molybdenum multi-metal ore: recommending beneficiation flowsheet according to the beneficiation test conclusion is that the copper-lead molybdenum mixes flotation, mixed floating mine tailing selects zinc, copper-lead molybdenum bulk concentrate separating flotation to select copper molybdenum bulk concentrate and lead concentrate, and copper-molybdenum concentrate is isolated copper concentrate and molybdenum concntrate again.Select the zinc stage at mixed flotation of copper-lead molybdenum and mixed floating mine tailing, in order to reduce the adverse effect of residual medicament in the backwater, the inventive method is mixed floating concentrate and tailings to the copper-lead molybdenum and is all adopted the backwater of dense dehydration, generation to return the use of the copper-lead molybdenum mixing section of sorting; In the zinc flotation flowsheet concentrate (zinc concentrate) and the mine tailing of this section also all adopted dense dehydration, made its backwater return zinc flotation section and use.And the like, select copper molybdenum bulk concentrate and lead concentrate stage at copper-lead molybdenum bulk concentrate separating flotation, the backwater that bulk flotation and lead concentrate floatation process produce respectively also returns the system that sorts accordingly separately.
Technical solution of the present invention has traditional backwater processing method effect that is beyond one's reach for the ore dressing of the listed four kinds of metallic ores of copper-lead zinc molybdenum of multiple metal such as the present invention.The method of ore-dressing of polymetallic ore factory backwater employing segmentation circulation has fundamentally been avoided the adverse effect between various medicaments, each section of the ion pair different process, the dehydration equipment that adopts is a concentrator, the control of reliable operation, easy operating has dropped to minimum with backwater to the influence of flow process.Compare with traditional technology, have reliable, energy-saving advantages, particularly process and need not add extra chemicals, avoided the generation secondary pollution.Adopt the method for segmentation backwater can solve the adverse effect of polymetallic ore backwater to mineral processing index.Beneficiation test is indicated; adopt the backwater of traditional backwater technology 80% and adopt mineral processing index copper recovery decline 2.66%, the zinc recovery of clear water to descend 8.64%; cupric all exceeds standard in lead, the zinc concentrate; adopt the present invention can farthest improve the impurity content of mineral processing index and product; also satisfy the relevant policies of State Environmental Protection Administration for environmental protection and prevention and cure of pollution when enterprise obtains good economic benefits, this method has very realistic meanings for the development of mines to ore character complexity.
