Activation can be roughly divided into: 1, spontaneous activation; 2, pre-activation; 3, reactivation; 4, vulcanization.
Spontaneous activation:
When the effect of the metal ore treatment, the surface of the grinding process some soluble mineral salt ions spontaneously multi colored, for example, sphalerite and copper sulfide intergrowth always a small amount of copper sulfide ores mined in the subsequent oxidation The substance is oxidized to copper sulfate, and the Cu2+ ion acts on the surface of the zinc ore to activate it, which makes it difficult to separate copper and zinc. It needs to be precipitated by adjusting agent such as lime or sodium carbonate, and some “inevitable ions†may cause activation. .
Pre-activation:
It means that in order to select a certain mineral, an activator is added to activate it. When the pyrite is heavier in oxidation, the oxide film on the surface of the pyrite is dissolved by sulfuric acid before the pyrite is selected to expose the fresh surface to facilitate flotation.
Resurrection:
It refers to a certain mineral that has been suppressed before, such as sphalerite suppressed by cyanide, which can be revived by adding copper sulfate.
Vulcanization:
It means that the metal oxide ore is first treated with sodium sulfide to form a thin film of metal sulfur mineral on the surface of the oxidized ore, and then floated with xanthate.
The ore dressing agents used as activators are:
Sulfuric acid, sulfurous acid, sodium sulfide, copper sulfate, oxalic acid, lime, sulfur dioxide, lead nitrate, sodium carbonate, sodium hydroxide, lead salt, barium salt, and the like.
