Description
(54) СПОСОБ ВЫЩЕЛАЧИВАНИЯ РУД И КОНЦЕНТРАТОВ(54) METHOD OF LEACHING OF ORES AND CONCENTRATES
ваетс способность поглощени кислорода воэауха, улучшаетс растворение реагентов в воое, происхопит окисление двухвалентного железа до трехвалентного и т.д.The oxygen absorption capacity of the wire is improved, the dissolution of the reactants in the boar is improved, the oxidation of bivalent iron to trivalent iron, etc. is performed.
Эти изменени , интенсифицирующие проuecQ вышелачивани руп и концентратов и снижающие расход кислоты, возникают в св зи с тем, что при движении раствора в магнитном поле в нем возникает эффект Хопла. За счет Холловской разности потенци алое в жидкости по вл ютс микротоки, привод щие к указанным №:ше изменени м. Дл увеличени этой разности потенциалов и усилени эффективности магнитной обработки предлагаетс примен ть посто нный электрический ток плотностью 0,01-0,1 а/м Ограничение тока по плотности вызвано тем, что действие электрическото тока начинает сказыватьс на интенсиБНб сти выщелачивани только при плотности выше 0,О1 а/м , а при плотности тока выше 0,1 а/мThese changes, which intensify the process of leaching of fluxes and concentrates and reduce acid consumption, arise from the fact that the Hopl effect arises when the solution moves in a magnetic field. Due to the Hall potential difference in the liquid, microcurrents appear, leading to the indicated no.: Changes. To increase this potential difference and increase the efficiency of magnetic treatment, it is proposed to use a constant electric current with a density of 0.01-0.1 a / The current density limitation is caused by the fact that the action of an electrical current begins to affect the intensity of leaching only at a density above 0, O1 a / m, and at a current density above 0.1 a / m
начинаетс разогрев раствора, снижающий эффективность магнитной обработки последнего .the heating of the solution starts, reducing the effectiveness of the magnetic treatment of the latter.
В св зи с тем, что зависимость эффективности магнитной обработки от величины напр женности магнитного пол имеет полиэкстремапьный характер, выбран оптимальный диапазон напр женности 0,5-0,7 кэ.Due to the fact that the dependence of the efficiency of magnetic treatment on the magnitude of the magnetic field strength is more extreme, there is an optimal range of intensity of 0.5–0.7 ke.
