Problems solved by technology

The useful mineral components in the existing gold, silver, lead, and zinc polymetallic ores have high grades and uneven particle size distribution. The conventional "gold, silver, lead flotation-tailings zinc separation" separation process for lead and zinc will have problems The following questions:
[0003] 1. Due to the high grades of lead and zinc in the raw ore and the close symbiosis, the conventional "gold, silver, lead flotation - tailings zinc separation" lead and zinc separation process cannot achieve efficient lead and zinc separation, resulting in lead concentrate and zinc concentrate The high mutual content of lead and zinc in the medium causes the loss of lead and zinc metals and affects the quality of lead concentrate and zinc concentrate products
[0004] 2. A large amount of zinc inhibitors need to be added in the production process of the conventional "gold, silver, lead flotation-tailings zinc separation" lead and zinc separation process. Excessive use of inhibitors will inhibit the associated gold and silver, resulting in a large amount of gold and silver precious metals Entering the follow-up zinc concentrate reduces the price coefficient of gold and silver and affects the economic benefits of the enterprise

Embodiment 1

[0023] A multi-metal ore distribution process containing gold and silver lead-zinc, including the following steps:

[0024] Step 1, after the original ore is 1 # ball mill grinder (depending on the degree of mineral dissociation depending on the mineral dissociation of different ore), the reselection machine is reselected, and the re-selection concentrate produced into the shaker is re-selected. Reselecting concentrate, reselecting medium ore 1 and reselecting medium mine 2;

[0025] Step II. After steps, the reselection tailings produced after the choice of the mine machine reselection is graded by a cyclone, and the cyclone overflow product and a cyclone sandstone product are obtained. Ball mill internal milling;

[0026] Step three, the cyclone overflow products obtained by step I will perform the gold and silver lead flotation work to obtain the tailings of gold and silver lead coarse intensity and gold and silver lead float;

[0027] Step four, the gold and silver lead coarse...

Embodiment 2

[0032] After 1 # ball mill grinding, the original mine entered the Nielsen + shaker reselection operation recovery monomer gold, silver (such as the ore without monomeric gold, silver, production can be omitted this operation), Nielsen retryed the tail mine fluid flow Rating, cyclone overflow products enter gold and silver lead flotation work, swirl sanding products return to milling; gold and silver lead flotation work coarse ore enters the shaker reselection operation, shake the bed reselection concentrate Three flotation selection operations received gold and silver lead concentrates, and the gold and silver lead flotation has entered the zinc-selected zinc operation after two sweeping operations. Re-selection operation, the shaker is retransmitted for three sellers to obtain zinc concentrates. It is selected from the selection of zinc. After three sweeping, the ricks are reselected and the coarse colry column shaker of the tailings and zinc coarse column shaker. After re-elect...

Abstract

The invention belongs to the technical field of beneficiation process methods, and particularly relates to a beneficiation process for polymetallic ore containing gold, silver, lead and zinc. The process comprises the steps of Nelson + table gravity separation operation, cyclone classification, gold, silver and lead flotation operation, gold, silver and lead rough concentrate table gravity separation operation, gold, silver and lead flotation tailings zinc separation operation, zinc rough concentrate table gravity separation operation, lead rough concentrate table tailings and zinc rough concentrate table concentrate grinding operation, lead of the lead rough concentrate table tailings and the zinc rough concentrate table concentrate, and zinc separation operation. The process is suitable for mineral separation of polymetallic ore containing gold, silver, lead and zinc, and lead and zinc are separated through a physical method according to the specific gravity difference of galena and sphalerite in the conventional mineral separation process of the polymetallic ore containing gold, silver, lead and zinc; and the technological process is simple, easy to implement and capable of being widely applied and popularized, and rich economic returns are obtained.

Description

Technical field [0001] The present invention belongs to the technical field of distribution process, and in particular, the present invention relates to a multi-metal ore distribution process containing gold and silver lead zinc. Background technique [0002] Zinc is widely used in various fields and is of great significance to industrial development. The lead-zinc multi-metal mine is complicated due to a wide variety of metals, and the composition of mineral composition is often accompanied by precious metals. Existing gold, silver, lead, zinc polymetallic mine has high levels of mineral components, uneven lack of grain size, lead, zinc separation process in conventional "gold and silver lead flotation - tail zenect" The following questions: [0003] 1. Because of the lead, the zinc is high and the symbiotic is closely related, the lead, zinc-zinc-zinc-zinc selection process is unable to achieve high-efficiency lead, zinc concentrate, resulting in lead concentrate, zinc concentr...
