    • The present invention relates, generally, to a method and apparatus for electrowinning metals, and more particularly to a method and apparatus for copper electrowinning using the ferrous/ferric anode reaction. In general, the use of a flow-through anode—coupled with an effective electrolyte circulation system—enables the efficient and cost-effective operation of a copper electrowinning system employing the ferrous/ferric anode reaction at a total cell voltage of less than about 1.5 V and at current densities of greater than about 26 Amps per square foot (about 280 A/m2), and reduces acid mist generation. Furthermore, the use of such a system permits the use of low ferrous iron concentrations and optimized electrolyte flow rates as compared to prior art systems while producing high quality, commercially saleable product (i.e., LME Grade A copper cathode or equivalent), which is advantageous.
    • 本发明一般涉及用于电解金属的方法和装置,更具体地涉及使用亚铁/三价铁阳极反应的铜电解提取方法和装置。 通常,使用与有效电解质循环系统耦合的流通阳极使得能够以小于约1.5的总电池电压对采用亚铁/三价铁阳极反应的铜电解冶金系统进行有效和经济有效的操作 V,电流密度大于约26安培/平方英尺(约280A / m 2),并减少酸雾产生。 此外,与现有技术的系统相比,使用这种系统允许使用低亚铁浓度和优化的电解质流速,同时生产高品质的商业可售产品(即LME A级铜阴极或等效物),这是有利的 。

    • The present invention is a system and method of biometric-based age verification for authorizing presenter access of age-restricted good or services between an age presenter and an age verifier. System presenters register at least one biometric identifier, at least one identification number, personal age-verifying data, and personal identity-verifying data. A presenter presents a biometric sample obtained from the presenter's person and the presenter's system ID number to conduct age verifications for purchase of or access to age-restricted goods or services. This data is used to authenticate the presenter's age and authorize access to purchase or obtain age-restricted goods or services by matching the presented transaction biometric with at least one registered biometric template and without the use of a man-made identity token.
    • 本发明是一种基于生物特征的年龄验证的系统和方法,用于授权演示者访问年龄呈现者和年龄验证者之间的年龄限制的商品或服务。 系统演示者至少注册一个生物特征标识符,至少一个识别号码,个人年龄验证数据和个人身份验证数据。 主持人提供从主持人的身份获取的生物特征样本和主持人的系统ID号码,以进行购买或访问年龄限制的商品或服务的年龄验证。 该数据用于对发言人的年龄进行认证,并通过将呈现的交易生物识别与至少一个注册的生物特征模板匹配并且不使用人造身份令牌来授权访问购买或获取年龄限制的商品或服务。
