Description
Technical field
The present invention relates to non-ferrous metal extraction technique field, specifically a kind of method from volcanics ion type rareearth ore recovering rare earth rich solution.
Background technology
The mineral deposit of ion type rareearth ore is mostly originated in sea level elevation and is less than 550m, the discrepancy in elevation is in the hilly country of 250 ~ 60m, with mild low mountain and aqueous development for feature, the grouan or the volcanics that are mainly exposed to ground are formed through long-term strong weathering, belong to exogenic mineral deposit, mineral deposit is generally in the distribution of face shape, cover on unweathered grouan or volcanics rock mass with lens-shaped, its structure can be divided into corruption to plant and eluvial layer from top to bottom, completely decomposed layer, half waste mantle, micro-waste mantle and basement rock, wherein the thickness of completely decomposed layer is maximum, the content of rare earth element is the highest.The occurrence status of ion type rareearth ore ore middle-weight rare earths is that the rare earth element of total amount 70% ~ 90% is adsorbed on the clay mineral in ore with the form of hydrated cation or hydroxy water cations, there is stable chemical property, outside deionization phase rare earth, other rare earth elements are water-dissolving phase, colloidal state phase, mineral facies are composed and deposited, and the rare earth element in current ion type rareearth ore only has ion type rareearth to have recovery value.
In ion type rareearth ore, current callable rare earth element exists with ionic adsorption form, the Typical physical beneficiation methods such as employing gravity treatment, magnetic separation, flotation cannot by its enriching and recovering, but these rare earth ions run into the more active positively charged ion of chemical property (as Na+, K+, H+, NH+4 etc.) time can exchanged desorb, therefore, when adopting containing this type of cationic solution (sodium-chlor or ammoniumsulphate soln etc.) eluent ion type rare-earth mineral, rare earth ion just can immersedly take out.Current, leaching technology experienced by three generations, the leaching technology of the third generation is injected in the fluid injection well of sealing treatment by head-tank by leaching agent, leaching agent is to the hole diffusion in ore body, and the rare earth ion exchanged being adsorbed on clay mineral surface is resolved, form rare earth mother solution and flow in intercepting gutter, treat that rare earth leaches complete, add top water to make to remain in the leaching agent in ore body and rare earth outflow, the lower concentration mother liquor formed gives reuse after treatment.
The leaching technology of the current third generation has two kinds of modes to flow in intercepting gutter by rare earth mother solution, and one is the water conservancy diversion tunnel of excavating the high about 1.6-1.8m in cross section, wide about 0.6-0.8m in half waste mantle and completely decomposed layer junction or completely decomposed layer; Two is the pressure release conduction holes of DN50mm of constructing at completely decomposed layer or completely decomposed layer and half waste mantle junction, the fluid injection well that these two kinds of modes are offered is all more shallow, about 50cm, two kinds of modes have following shortcoming: (1) tunnel is arranged on half waste mantle and completely decomposed layer junction or completely decomposed layer, cause completely decomposed layer can adopt rare earth resources amount excavate due to tunnel and lose, half waste mantle can be adopted rare earth resources and derived by pressure release in tunnel due to ore leachate and cannot enter half waste mantle leaching rare earth, and two aspects cause rare earth mining recovery low.(2) tunnel is arranged on half waste mantle, again because hard cannot the driving of half waste mantle lithology can realize.(3) rare earth resources can be adopted below conduction hole and cannot leach recovery.(4) part leaching ore deposit rich solution is permeated below pod apertures by the interlayer between pod apertures, causes rare earth rich solution to lose.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of method from volcanics ion type rareearth ore recovering rare earth rich solution, the method can overcome the shortcoming of aforesaid way, improves the rate of recovery leaching rare earth rich solution.
The technical solution adopted in the present invention is: provide a kind of method from volcanics ion type rareearth ore recovering rare earth rich solution, offer the water conservancy diversion tunnel of cross section height 1.6-1.8m, wide 0.6-0.8m at ore body completely decomposed layer near half waste mantle side, water conservancy diversion tunnel length extends to half waste mantle; Offer the pod apertures of diameter 50 ~ 80mm at ore body half waste mantle near micro-waste mantle side, pod apertures length extends to micro-waste mantle; Ore body is arranged for filling with the fluid injection well drenching ore leachate.
Described pod apertures establishes 1 ~ 2 layer, and pod apertures becomes the angle of 1-5 ° with horizontal plane, pod apertures interlamellar spacing 50cm ~ 500cm, pitch of holes 40 ~ 150cm.
The degree of depth of described fluid injection well is the thickness of completely decomposed layer.
The mode that the present invention combines from the method for volcanics ion type rareearth ore recovering rare earth rich solution by offering water conservancy diversion tunnel and conduction hole, namely the completely decomposed layer adopting collection pond, tunnel mode to cause is avoided can to adopt the loss of rare earth resources amount, can adopt below pod apertures can be avoided again to be arranged on pod apertures that completely decomposed layer causes that rare earth resources cannot leach recovery, part leaching ore deposit rich solution is permeated below pod apertures by the interlayer between pod apertures, cause the shortcoming that rare earth rich solution loses, the method improve the effect of leaching ore deposit and drainage, improve the rate of recovery leaching rare earth rich solution.
