专利汇可以提供Flotation of copper and nickel sulfides from talcose bearing ores专利检索，专利查询，专利分析的服务。并且A method for the flotation of nickel and copper sulphide minerals from talcose bearing ores using an alkaline circuit in which at least one of the alkaline reagents is soda ash or ammonium hydroxide and following conditioning of the pulp with a collecting agent of the xanthate family to activate the nickel and copper sulphide materials, the pulp is conditioned with a flocculating agent to depress the host rock minerals and in which following flotation the rougher concentrate is further conditioned with a dispersant or a flocculant prior to the first cleaner float.，下面是Flotation of copper and nickel sulfides from talcose bearing ores专利的具体信息内容。

权利要求

1. A process for the flotation of nickel and copper sulphide minerals from talcose bearing ores comprising producing an alkaline pulp of the ore in a suitable state of subdivision for flotation wherein at least one alkaline reagent present is soda ash or ammonium hydroxide and the pH is within the range of from about 8 to about 10.5, conditioning the resultant pulp with a collecting agent of the xanthate family until the nickel and copper minerals are activated, adding a flocculating agent for the talcose host rock materials together with a frother and conditioning the pulp to depress the talcose host rock materials, subjecting the thus produced pulp to froth flotation to produce a rougher concentrate, repulping the rougher concentrate with the additiOn of a further reagent selected from the group consisting of dispersants and flocculants for the talcose host rock materials and conditioning the thus produced pulp to further depress the talcose host rock materials, and subjecting the thus produced pulp to a cleaner float to produce a first cleaner concentrate relatively rich in nickel and copper sulphide minerals and relatively poor in talcose host rock ingredients.

2. A process for the flotation of nickel and copper sulphide minerals from talcose bearing ores comprising wet grinding the ore to produce an alkaline pulp thereof in a suitable state of subdivision for flotation wherein at least one alkaline reagent present is soda ash or ammonium hydroxide and the pH is within the range of from about 8 to 10.5; conditioning said pulp with a collecting agent of the xanthate family in the presence of a flocculating agent for the talcose host rock materials to activate the nickel and copper minerals and depress the talcose host rock materials; further conditioning said pulp with a frother and subjecting the same to froth flotation to produce a rougher concentrate; repulping the rougher concentrate with the addition of further flocculating agent for the talcose host rock materials and conditioning the thus produced pulp to further depress the talcose host rock materials, and subjecting the thus produced pulp to a cleaner float to produce a first cleaner concentrate relatively rich in nickel and copper sulphide minerals and relatively poor in talcose host rock ingredients.

3. A process as claimed in claim 1 wherein the reagent selected from the group consisting of dispersing agents and flocculating agents for the talcose host rock materials after the rougher concentrate is repulped is a dispersing agent for the talcose host rock materials.
