总述 采用“三段一闭路破碎+球磨+异步浮选+精矿再磨+浓缩过滤两段脱水”的工艺流程，是符合艾娜克铜矿特点的节能省耗的先进成熟流程； 采用世界先进的大型高效设备； 原矿有用组分单一，铜的回收率高； 原矿中无As、Hg等有害杂质，无辐射性，厂房内含尘浓度达到工作标准，所添加的选矿药剂无毒且用量小，药剂在尾矿库内会自然氧化分解，尾矿水可回用于选矿厂而不外排，选矿过程和选矿废弃物是安全环保的。 |

Summary The process followed as:“three-step-one-circuit pulverizing + ball milling + asynchronous floatation+ re-milling of refined minerals + concentrating and filtrating with two segment dehydration” has been confirmed to be an advanced mature process which is both energy-saving and consumption-reduing.These keep with the characteristics of Aynak copper mine; The world’s most advanced equipment is applied.which is also large-size and high efficient. useful component of the origin minerals is single and the recovery rate of the copper is high. There is no harmful impurities such as As, Hg, etc, and no radiation, the dust concentration in the workshop reached standard, small amount medicaments was used as additive for mineral selection and its nontoxic. the used medicaments will be naturally oxidated and decomposed at the gangue storehouse; the water of the gangue will be recycled to mineral selection factory without leakage; the process of mineral select and the wastes after the selection are safe and environmentally-friendly. |

Summary The process flow featured “three-step-one-circuit pulverizing + ball milling + asynchronous floatation+ re-milling of refined minerals + concentrating and filtrating with two segment dehydration” has been confirmed to be an advanced mature one that is both energy-saving and consumption-reduing which complies with the characteristic of Aynak copper mine; The world-class top-performance large equipment with high efficiency is used. Single useful component of the origin minerals and high recovery rate; No harmful impurities such as As, Hg, etc, no radiation, qualified dust concentration in the workshop, small amount nontoxicate medicaments used as additive for mineral selection; the used medicaments naturally oxidated and decomposed at the gangue storeroom; thegangue water recycled to mineral selection factory without leakage; the procedure of mineral processing and the consequent wastes are safe and environmentally-friendly. |

the process of " 3-segment and one closed loop of crushing+ball milling+asynchronous flotation selecting+refined mineral regrinding+two-stage dewatering with concentrating and filtering" is advanced and mature with the energy saving and low consumption characteristics of Aina Ke copper mine; using the advanced, large and highly efficient equipment in the world; the original mineral possesses the single useful ingredient and the recycle rate of copper is high; the original mineral has neither harmful impurities such as As, Hg and etc or redioactivity. the dust concentration in the workshop is within the work standards. the added reagents used for the mineral selection are non-toxic and the used amount is small. in addition, the reagents would naturally be oxidized and decomposed in the reservoir of the tail mineral. water of the tail mineral could be re-used in the plant for mineral selection rather than discharged outside. both the process of the mineral selection and wastes produced in the mineral selection are safe and environmental protective.
