Abstract

The utility model discloses a fine particle disseminated type primary gold ore selecting and smelting apparatus. The utility model is characterized in that reactors are evenly arranged in a smelting furnace which is made of fireproofing materials; one side of each of the reactors is connected with a burner via a flame path, and the other side of each of the reactors is connected with a gas outlet path via a flue. The utility model solves the problem that in the process of selecting and smelting, gold elements easily escape with other elements jointly; the quality of primary ore can be changed, ore bodies are oxygenized, and via utilizing the existing cyanidation technology, the leaching rate of the ore bodies is over 85%. The utility model has the advantages of low production cost and simple process.

Description

Microfine infects type raw gold ore smelt-collecting equipment

The utility model relates to a kind of equipment that uses for the selecting and smelting technology of gold mine, the particularly equipment that selects the Technology Need of smelting to use for the micro-grain impregnation raw gold ore.

The ore that microfine infects the type raw gold ore is divided into two types: primary ore and oxidized ore, and this is wherein again based on primary ore; For oxidized ore, domestic and international equal selecting and smelting technology of existing comparative maturity, and for the primary ore that occupies main reserves,, still can not obtain at present utilizing in default of effective selecting and smelting technology, mineral products can only can not be brought into play it as slow-witted ore deposit that effect should be arranged; For primary ore, if its reaction can be oxidized ore, the method of then taking to pile up the cyaniding processing just can extract gold, and primary ore is converted to the difficult problem that oxidized ore has two aspects: the one, and how tens kinds of elements that coexist with gold element in the ore separate with gold element; The 2nd, form parcel after separating again, how about this parcel opened, gold element is separated; At present, the many research institutions of China are studied, many smelting stoves that select have been designed, but owing to all do not grasp correct smelting process, the crucial technical parameter of control, make that gold element can be with waste gas, waste water " escape " in carrying out smelting process in the ore, the rate of recovery of these equipment is lower, production cost is high, does not have economic worth, up to now, micro-grain impregnation raw gold ore smelt-collecting equipment also is among the research.

The purpose of this utility model is: a kind of micro-grain impregnation raw gold ore smelt-collecting equipment is provided, this equipment solved select gold element in the smelting process easily with other element problem of " effusion " jointly, utilize it can make primary ore qualitative change, ore body oxidation and avoid forming once more inclusion, utilize existing cyanidation technique, its leaching yield reaches more than 85%, its production cost is low, technology is easy, the economic worth height.

The utility model is to constitute like this: evenly distributed reactor (2) in the smelting furnace that is made of refractory materials (1), one side of reactor (2) connects burner (5) by quirk (3), the opposite side of reactor (2) connects gas off-take (5) by flue (4), discharge port (7) is arranged at the bottom of reactor (2), reactor (2) has one group at least, and two groups of above reactors (2) are communicated with by flue (4).

The utility model solved select gold element in the smelting process easily with other element problem of " effusion " jointly, can make primary ore qualitative change, ore body oxidation and avoid forming once more inclusion, utilize existing cyanidation technique to extract again, its leaching yield reaches more than 85%, its production cost is low, technology is easy, the economic worth height has reached goal of the invention of the present invention.

Accompanying drawing 1 is an equipment front view of the present invention, and accompanying drawing 2 is the vertical view of present device.

Embodiment 1 of the present utility model: evenly distributed two rows, each 8 annular reactor (2) of every row in the smelting furnace that constitutes by refractory brick (1), one side of reactor (2) connects coal stove burner (6) by quirk (3), the opposite side of reactor (2) connects gas off-take (5) by flue (4), discharge port (7) is arranged at the bottom of reactor (2), and reactor (2) has one group; During use primary ore carried out after the ore dressing broken, then primary ore is put into reactor (2), point coal furnace burner carries out calcination, when calcination, last 1/3rd sections temperature of reactor (2) is controlled to be 400 degrees centigrade, a temperature of/3rd sections in the reactor (2) is controlled to be 800 degrees centigrade, following 1/3rd sections temperature of reactor (2) is controlled to be 1200 degrees centigrade, then primary ore is put into reactor (2) calcination from the top of reactor (2), the time that primary ore reacts in reactor (2) is 4 hours, and to utilize caliber simultaneously be 1.5 centimetres pipe, being pressed into pressure is 2 atmospheric industrial oxygens, ore after the calcination is from discharge port (7) discharging, being cooled to the ore temperature is to put into the pond behind the normal temperature to carry out the processing of cyanogen bubble, the time of soaking is 72 hours, carrying out your liquid then reclaims, carry out charcoal absorption afterwards, at last it is resolved gold.

Embodiments of the invention 2: evenly distributed two rows, each 10 annular reactor (2) of every row in the smelting furnace that constitutes by refractory brick (1), one side of reactor (2) connects electric burner by quirk (3), the opposite side of reactor (2) connects gas off-take (5) by flue (4), and the bottom of reactor (2) has discharge port (7) reactor (2) to have two groups; Using method is identical with embodiment.
