摘要: By suppressing oxidation of sulfide minerals in sulfide ore due to bacteria or the like, this invention prevents the elution of heavy metals from the sulfide ore, and reduces the decrease in flotation performance when processing sulfide ore that is stored in a stockpile. Also, the invention makes it easier to process acidic wastewater from a stockpile or tailings dumpsite. In order to accomplish this, oxidation of sulfide minerals in sulfide ore is suppressed by adding an antioxidant, which contains plant polyphenol and whose main component is an organic acid that contains a carboxyl group, to the sulfide ore stored in a stockpile or tailings dumpsite.

摘要: The present invention concerns a method of separating variable ores containing copper, lead, zinc and the like as the refining material for non-ferrous metals and gangue minerals such as pyrite, quartz, feld spar and the like from dug out ores and, particularly, it relates to a flotation method. For obtaining non-ferrous metal valuable ores as concentrates from ores by a flotation method, flotation is conducted by using gaseous sulfurous acid or aqueous sulfurous acid as a depressant for controlling the floatability of pyrite. The flotation method comprises measuring the redox potential of an ore solution before and after the addition of gaseous sulfurous acid or aqueous sulfurous acid and determining an optimum addition amount by utilizing a proportional relationship present between the difference of the potential and the valuable quality enhancing rate. According to the method, it is possible to judge the effect of depressing pyrite, that is, the effect of sulfurous acid for enhancing the valuable quality without complicate analysis or test and, further, when the method is applied to automatic control, an utmost economical merit can be obtained by quality control of concentrates or saving of wasteful consumption of the reagent.

摘要: The screw comprises a circular thread portion 2a formed in a base portion of the screw, in which a helical thread is formed at the same depth and at the same crest angle; a special non-circular thread portion 2b which follows the portion 2a and has its thread depth gradually vary so as to assume a polygonal shape in cross section and permit the crest portion of thread to reach its highest points A-J in a turn of the thread, the highest points A-J being equal in thread depth and crest angle to the thread of the portion 2a; the portion 2b has its crest angle gradually increase as the thread moves from the highest points A-J to its lowest points along the length of the thread; and, lines connecting axially adjacent ones of the highest points A-J are tilted from the axis of the screw at a predetermined angle so that the portion 2b assumes a twisted polygonal prism-like shape as a whole.
