在铜火法冶金行业，一种方法是由硫化物铜精矿间接生成粗铜， 这种方法 一般包括两个步骤：首先将硫化物铜精矿进行脱硫除铁，熔炼得到高品位铜锍， 然后将得到的铜锍进一步脱硫除铁， 吹炼得到粗铜。 另一种方法是釆用铜精矿 直接生产粗铜， 在实际生产中， 澳大利亚的 Olympic Dam 冶炼厂、 波兰的 Glogow冶炼厂以及赞比亚的 KCM冶炼厂釆用的就是由铜精矿直接生产粗铜 的工艺。 这些铜冶炼的方法生产得到的粗铜含铜一般为 98.5% (重量比）， 但 是， 这些方法还具有一个共同的特点， 就是在生产所得炉渣中， Cu20和 Fe304 的量都较高，一般说来，铜含量为 10%~20%(重量比 ) , Fe304含量为 30%~50% (重量比）， 这会造成资源的大量浪费。

与现有技术相比， 本发明将铜冶炼熔融炉渣和含碳还原剂引到生产装置 中， 并向所述生产装置中导入带压力的惰性气体， 所述惰性气体的压力为 100kPa~800kPa, 混合后进行反应， 得到粗铜和反应后的炉渣。 本发明利用铜 冶炼熔融炉渣的显热使含碳还原剂达到炽热状态，通过所述炽热的含碳还原剂 将炉渣中的 Cu20还原成金属铜， 同时将炉渣中的 Fe304还原成 FeO; 导入的 惰性气体对反应物料形成强烈的搅拌，使熔融炉渣沸腾， 并将含碳还原剂卷入 熔融炉渣中， 促使生成的金属铜小液滴相互结合， 形成分开的粗铜相和渣相。 本发明通过惰性气体的强烈搅拌，促进反应界面的快速更新，强化了反应进程， 使渣性迅速被改变，降低渣粘度，在提高金属铜液滴间的碰撞结合几率的同时， 有利于金属铜液滴的沉降， 因此， 本发明在强化过程能得到粗铜， 并且使最终 炉渣中的铜含量降低。 实践表明， 本发明能生产得到含铜量大于 98.5% (重量 比） 的粗铜， 最终炉渣中的铜含量降低到 0.4% (重量比） 以下。 附图说明 图 1为本发明实施例提供的用于粗铜生产的生产装置的结构示意图。 具体实施方式
为了进一步理解本发明， 下面结合实施例对本发明优选实施方案进行描 述， 但是应当理解， 这些描述只是为进一步说明本发明的特征和优点， 而不是 对本发明权利要求的限制。
本发明提供了一种粗铜的生产方法， 包括以下步骤：
在生产装置中，将铜冶炼熔融炉渣和含碳还原剂及带压力的惰性气体混合 后进行反应， 得到粗铜和反应后的炉渣； 所述惰性气体的压力为 100kPa~800kPa„
为适应冶金工艺的发展，克服现有技术的不足， 本发明提供的粗铜的生产 方法是一种由铜冶炼过程中产生的富含 Cu20和 Fe304的熔融炉渣直接生产粗 铜的方法， 不但能得到粗铜， 而且能降低处理后的炉渣中的含铜量， 使最终炉 渣无需再进行选矿等处理，粒化后即可作为其他工业的原料，投资和生产成本 较低。 因此， 本发明所述方法也可以说是一种铜冶炼熔融炉渣贫化的方法。
本发明实施例将铜冶炼熔融炉渣和含碳还原剂引到生产装置中，并向所述 生产装置中导入带压力的惰性气体， 所述惰性气体的压力为 100kPa~800kPa, 混合后进行反应， 得到粗铜和反应后的炉渣。
本发明以铜冶炼熔融炉渣为原料生产粗铜 ,具有较高的经济效益和社会效 益。 所述铜冶炼熔融炉渣为本领域技术人员熟知的铜冶炼过程中产生的富含 Cu20和 Fe304、呈熔融状态的炉渣。本发明对所述铜冶炼熔融炉渣的组分没有 特殊限制， 其中， 铜是氧化态的， 含量一般为 10%~20% (重量比）； Fe304— 般为含量为 30%~50% (重量比）。 所述铜冶炼熔融炉渣具有显热， 其温度优选 为 1050°C~1350°C：。 本发明利用铜冶炼熔融炉渣的显热使含碳还原剂达到炽热 状态， 无需补充额外的热量来帮助含碳还原剂升温， 节能效果较好， 节省经济 成本。
本发明釆用含碳还原剂与所述铜冶炼熔融炉渣混合， 将炉渣中的 Cu20还 原成金属铜， 同时将 Fe304还原， 得到粗铜、 且使炉渣贫化。 所述含碳还原剂 呈粒状， 优选为煤炭和焦炭中的至少一种， 更优选为焦炭； 本发明对其来源没 有特殊限制。在本发明中， 所述含碳还原剂中含碳量与所述铜冶炼熔融炉渣中 含氧量之比 （C/0 )优选为 （0.1~0.35 )： 1 (质量比）。
本发明通过向上述反应物料中导入带压力的惰性气体，提供使熔融炉渣沸 腾和产生强烈的搅拌作用的动力。具体说来， 导入的惰性气体对反应物料形成 强烈的搅拌， 使熔融炉渣沸腾， 并将含碳还原剂卷入熔融炉渣中， 促使生成的 金属铜小液滴相互结合， 形成分开的粗铜相和渣相。
本发明通过惰性气体的强烈搅拌，促进反应界面的快速更新， 强化了反应 进程， 使渣性迅速被改变， 降低渣粘度， 在提高金属铜液滴间的碰撞结合几率 的同时， 有利于金属铜液滴的沉降， 因此， 本发明此强化过程能得到粗铜， 并 且使最终炉渣中的铜含量降低。 另外， 釆用惰性气体进行搅拌， 能避免含碳还 原剂和生成的粗铜被氧化， 降低含碳还原剂的使用量， 效率较高， 成本较低。
在本发明中， 所述惰性气体的压力为 100kPa~800kPa , 优选为 200kPa~600kPa, 更优选为 300kPa~500kPa。 所述惰性气体优选为氮气， 增加 反应物料之间的接触， 提高反应效率， 同时氮气作为惰性气体不会将还原的 Cu和 FeO再次被氧化， 利于粗铜生产。
本发明优选将铜冶炼熔融炉渣引到生产装置中， 按比例加入含碳还原剂， 并向所述生产装置中导入带压力的惰性气体。在本发明中， 所述生产装置优选 釆用以下的生产装置。
本发明提供了一种用于粗铜生产的生产装置， 包括：
炉体， 所述炉体内包括熔池， 所述炉体上设置有气体喷嘴、 加料口、 粗铜
4非放口和炉渣 4#放口；
所述气体喷嘴设置于所述炉体的侧墙上， 且通向所述熔池的中部。
本发明提供的生产装置用于粗铜生产，利于得到粗铜和降低处理后的炉渣 中的含铜量。
本发明实施例提供的用于粗铜生产的生产装置为侧吹冶金炉，其结构参见 图 1 , 图 1为本发明实施例提供的用于粗铜生产的生产装置的结构示意图。
在图 1中， 1为铜冶炼熔融炉渣， 2为含碳还原剂， 3为带压力的惰性气 体， 4为炉体， 411为气体喷嘴， 412为燃料烧嘴， 413为加料口， 414为上升 烟道， 415为粗铜排放口， 416为炉渣排放口， 5为燃料， 6为助燃剂， 7为未 反应的含碳还原剂层， 8为炉渣层， 9为粗铜层。
在本发明中， 炉体 4内包括熔池， 主要在其中进行粗铜生产。 在本发明的 一个实施例中， 炉体 4内还包括与所述熔池相通的上升烟道 414, 生产过程中 产生的炉气由上升烟道 414排出， 经过降温、 除尘后排空。
炉体 4上设置有加料口 413 , 通过其加入铜冶炼熔融炉渣和含碳还原剂。 作为优选，铜冶炼熔融炉渣 1和含碳还原剂 2分别通过流槽由加料口 413引到 生产装置中。
炉体 4上设置有气体喷嘴 411 , 其位于炉体 4的侧墙上， 且通向所述熔池 的中部； 所述熔池的中部也就是形成的渣层所对应的位置。 气体喷嘴 411可以 位于炉体 4的一个侧墙上， 也可以位于炉体 4的两个侧墙上。 在本发明中， 一 个侧墙上的所述气体喷嘴的数量可以为 1个或多个， 优选为 5个。
在本发明中， 惰性气体 3优选通过气体喷嘴 411导入生产装置中。 由于气 体喷嘴 411位于炉体 4的侧墙上， 且能浸没于熔池的熔体中， 也就是能导入渣 层中， 导入的惰性气体 3 能更好地提供使熔融炉渣沸腾和产生强烈搅拌的动 力， 不会将产物重新搅起而进入炉渣， 利于产物的沉降、 分离， 效率较高。
在本发明的一个实施例中， 炉体 4的顶部设置有燃料烧嘴 412 , 向其中导 入燃料 5和助燃剂 6。本发明优选通过在燃料烧嘴 412内燃烧燃料 5产生热量， 另外， 炉渣中的 Cu20和 Fe304与含碳还原剂 2反应时， 会产生一定量的 CO (未在图 1中示出）， 产生的 CO与空气和助燃剂 6燃烧也产生热量， 所述空 气由加料口 413吸入，产生的这些热量可维持还原反应的热平衡。 所述燃料釆 用本领域常用的即可； 所述助燃剂优选为氧浓度大于 95% (重量比）的工业氧 气， 以保证较小的炉气量， 从而使由炉气带走的热量损失足够小。 本发明对所 述燃料和助燃剂的用量没有特殊限制，燃烧产生的总热量能维持还原反应的热 平衡即可。
在本发明中， 炉体 4上设置有粗铜排放口 415 , 其位于炉体 4的侧墙的下 部， 所述侧墙的下部也就是形成的粗铜层所对应的位置。 粗铜由粗铜排放口 415排出， 可导入到阳极精炼炉中进行粗铜精炼。
在本发明中， 炉体 4上设置有炉渣排放口 416, 用于排放炉渣。 在本发明 的一个实施例中，加料口 413位于炉体 4的一端的顶部， 可成比例地连续加入 反应物料， 而炉渣排放口 416位于炉体 4的另一端的下部，新炉渣由此连续排 出并可被粒化， 用作其他工业的原料。
本发明对所述炉体、 气体喷嘴、 燃料烧嘴的材质和尺寸没有特殊限制， 釆 用本领域常用的即可。 所述加料口、 炉渣排放口、 粗铜排放口、 熔池和上升烟 道的尺寸为本领域技术人员熟知的技术内容， 本发明对此也无特殊限制。
本发明实施例进行粗铜生产时，在炉体 4的一端，铜冶炼熔融炉渣 1通过 流槽由加料口 413引到炉体 4中，通过流槽由加料口 413按比例加入含碳还原 剂 2, 并通过炉体 4的两个侧墙上的、 浸没于熔池的熔体中的气体喷嘴 411连 续导入带压力的惰性气体 3 , 使熔融炉渣沸腾， 并将粒状的含碳还原剂卷入熔 融炉渣中， 形成混合体。
在此过程中， 炉渣的显热使含碳还原剂达到炽热状态，通过此炽热的含碳 还原剂， 炉渣中携带的铜的化合物 Cu20被还原成金属铜； 炉渣中携带的铁的 化合物发生转变， 由高熔点的 Fe304转化为 FeO, 进一步的 FeO与炉渣携带的 Si02造渣， 形成更低熔点的 2FeO · Si02, 使炉渣的性质发生转变， 粘性降低， 利于铜与炉渣的沉降、 分离。 而导入的惰性气体对反应物料形成强烈的搅拌， 促进反应界面的快速更新， 强化了反应进程， 使渣性迅速被改变， 同时促使生 成的金属铜小液滴相互结合， 在炉体 4内形成分开的炉渣层 8和粗铜层 9。
富余的未反应的含碳还原剂因其较轻的比重漂浮在渣面上，形成固态炽热 的未反应的含碳还原剂层 7。 固相的未反应的含碳还原剂层 7将液相的炉渣层 8、 粗铜层 9与上部的空气层相隔离， 杜绝渣层中的 FeO和粗铜层中 Cu与空 气层中 02的接触， 保证了还原后的铜、 炉渣不会被重新氧化。
并且， 本发明实施例向设置于炉体 4顶部的燃料烧嘴 412 中导入燃料 5 和助燃剂 6, 通过在其中燃烧燃料 5以及 CO的燃烧维持还原反应的热平衡， 而用于燃料 5燃烧的助燃剂 6是工业氧气， 其氧浓度大于 95% (重量比 ) , 以 保证较小的炉气量， 从而保证由炉气带走的热量损失足够小。
在炉体 4的另一端， 液相的炉渣通过炉渣排放口 416排出， 而炉体 4的侧 墙的下部的粗铜排放口 415排出液相的粗铜。 另外， 上述过程中产生的炉气由 上升烟道 414排出， 经过降温、 除尘、 脱石克后排空。
生产完成后， 得到分开的粗铜和新炉渣。 按照本领域的检测标准， 所述炉 渣含铜在 0.4% (重量比） 以下， 其粒化后可作为其他工业的原料； 所述粗铜 含铜大于 98.5% (重量比 ), 可导入到阳极精炼炉进行粗铜精炼。
综上所述， 本发明提供的粗铜的生产方法反应效率高， 釆用铜冶炼熔融炉 渣生产得到粗铜，且尾渣含铜低。另外，本发明所述方法不但工艺简单，控制、 操作方便， 而且设备小， 能耗低， 投资少， 适于推广。 及用于粗铜生产的生产装置进行具体描述。
