Embodiment 1

[0044] A gold and copper flotation mixed concentrate mainly includes chalcopyrite, and a small amount of bornite, pyrite, arsenopyrite, native gold, silver-gold ore, argentite, etc.; the non-metallic minerals contained are mainly quartz and Dolomite, followed by calcite and kaolinite. Most of the copper minerals are chalcopyrite, and there is a small amount of bornite. Chalcopyrite mainly exists in the form of monomer, and secondly, it is associated with gangue, and occasionally it can be seen associated with gold and pyrite. Gold exists as free monomer natural gold, accounting for 80.25% of the total gold, and the gold that is dispersed in copper minerals and pyrite as gold joints accounts for 13.50% and 4.20% of the total gold respectively; gold in gangue Accounting for 2.05% of the total gold. Its multi-element analysis is shown in Table 1

Abstract

The invention belongs to the field of mineral separation, and particularly relates to a separating method for gold and copper floating bulk concentrate. The separating method comprises the following steps: (1) breaking hydrophobic floccules of gold and copper floating bulk concentrate; (2) eliminating organic substances in a solution, and keeping an aqueous solution clean; (3) performing primary pre-separation on the gold and copper floating bulk concentrate; (4) grinding and dissolving part of gold and copper aggregates; (5) conveying ore pulp in the step (4) to a hydrocyclone to grade; (6) purifying gold rough concentrate and recycling part of copper pyrites; and (7) conveying gold concrete pulp in the step (6) to a settling pond to settle, and directly purifying and refining obtained gold concentrate (natural gold particles); conveying copper concentrate I, copper concentrate II and copper concentrate III to a dehydrating system which is composed of a thickener and a filter to dehydrate qualified copper concentrate as smelting copper-extracting raw materials, and recycling a little gold contained in the copper concentrate. The separating method can separate gold and copper bulkconcentrate to obtain gold and copper concentrate with stable and reliable indexes.

Description

technical field [0001] The invention belongs to the field of mineral processing, and in particular relates to a method for separating gold and copper flotation mixed concentrates. Background technique [0002] Mineral beneficiation is the process of separating useful minerals from useless or harmful minerals in mineral raw materials by physical or chemical methods, or separating a variety of useful minerals, also known as "mineral processing", the term for the enrichment of useful components in products Concentrates are tailings enriched with useless components. The concentrates provided by ore dressing are mainly used as raw materials for metal extraction in the smelting industry. Magnetic separation is a method of separating useful minerals from minerals according to the different magnetic properties of minerals. High-gradient magnetic separators are effective for processing fine-grained paramagnetic minerals, especially for weak magnetic separation of iron ore. With the d...
