摘要： The invention uses machine-vision to improve the performance of a flotation operation to provide a substitute for conventional human vision and problem-solving abilities. The invention redirects the conventional approach of "characterising the froth" to "measuring the froth characteristics". The invention provides a method of monitoring and controlling a mineral mixture flow in a froth flotation cell of a flotation plant which includes the steps of obtaining a series of digital images extracted of froth characteristics from a flotation cell. The digital images are transmitted to a computer for processing thereof into parameter signals of digital parameter froth characteristics. Control signals are produced in response to parameter signals received for causing required variations in froth characteristics in a flotation cell; and the froth characteristics in the flotation cell are controlled in response to the control signals so as to cause required variations in the froth characteristics in the cell.

摘要： The invention relates to a method for controlling a process operating by means of the electrochemical potential, in which process complex ores and/or concentrates are treated in order to arrange the valuable components in the materials in a form appropriate for further processing and in which method electrodes made of material essentially similar to the materials to be treated in the process. According to the invention an impedance analysis in connection with the measurement of the electrochemical potential is carried out for the material to be treated in process in order to analyze the state of the solid surface and/or the state between the solid material and the intermediary material. The measured values are utilized in the adjustment of the process parameters. In order to carry out the impedance analysis voltage pulses are conducted into the material in at least one frequency and in at least one value of the electrochemical potential of the material.

摘要： Flotation of sulphide minerals from their ores is achieved by a process in which two or more conditioning steps are carried out prior to a froth flotation step. The first step comprises conditioning a pulp of the ore in the presence of at least one alkaline agent selected from a group of agents which is defined in the specification which follows. The pulp is then further conditioned in the presence of a member of the xanthate family of flotation reagents and sufficient dispersing agent to effectively disperse the host rock minerals. The resulting pulp is then subjected to froth flotation. Preferably there are three separate conditioning steps, namely conditioning carried out in the presence of (1) one of the hereinafter defined alkaline agents, (2) a member of the xanthate family of flotation reagents, and (3) sodium silicate. The invention is particularly valuable for the recovery of metallic sulphides from ores containing talcy minerals or natural slimes and the invention has been applied with signal success to the flotation of copper-nickel sulphide ores containing over 40 percent weight of talcose host rock minerals.

摘要： Copper sulphide concentrate is recovered from an ore containing sulphides of copper and of iron by floating the ore to obtain a rougher concentrate containing a major proportion of the recoverable copper sulphide, separating the concentrate into sands and slimes, treating the sands in an alkaline state with a soluble cyanide and subjecting the treated sands to a flotation operation whereby the copper sulphide content of the sands is in large part recovered in the resulting concentrate and flotation of the iron sulphide content is in large part inhibited. Essentially, the ore is ground to about minus 65 mesh and the ground ore is the subject to a rougher flotation operation. The rougher float tails are passed through a scavenger float, the tails from this scavenger float being discarded and the concentrate usually, but not necessarily, being reground and returned to the rougher float. The rougher float concentrate is separated in a hydrocyclone into sands and slimes. The sands are treated with a soluble cyanide in the presence of lime or with crude calcium cyanide and, preferably after regrinding, are floated to produce a finished concentrate and tails. The tails either directly or after a scavenger float may be discarded, or directly or after the scavenger float recycled to the sand-slime separation step or fed back to the rougher float. The separated slimes may be added directly to the sand flotation step, or they may be sent to a smelter with the finished sand concentrate, or they may be floated separately the concentrate being sent to the smelter and the tails being discarded directly or after a scavenger float. The slimes scavenger float concentrate is recycled, preferably to the rougher float. Examples of modifications of the process are given and proportions of cyanide and line are specified. The preferred soluble cyanide is crude calcium cyanide, but sodium cyanide, hydrocyanic acid, and other alkali or alkaline earth cyanides or organic cyanides, e.g. lactonitrile, may be used.
