The present invention provides a process for producing aluminum hydroxide with little contamination by silica at a high yield, while suppressing losses of consumed alumina and alkaline components. The process comprises the steps of mixing a first alumina-containing slurry with a preheated alkaline aqueous solution, extracting alumina from the mixture, separating a dissolution residue from the mixture to obtain a solution, mixing the solution with a second alumina-containing slurry, extracting alumina from the mixture, and precipitating aluminum hydroxide after a desilication treatment.
摘要:
In a process for extracting alumina from alumina-containing ores by individually preheating a slurry of alumina-containing ores in alkali solution, and an alkali solution, and feeding the preheated slurry and the preheated alkali solution to a digester maintained at a temperature of about 200.degree. to about 300.degree. C, thereby extracting alumina from the alumina-containing ore. The alumina extraction is carried out without any formation of scales on the inside surface of the preheater with a considerably prolonged operating duration by preparing a slurry having a molar ratio of Na.sub.2 O/Al.sub.2 O.sub.3 of not more than 1 from the alumina-containing ores and an alkali solution, subjecting the slurry to preliminary desilication treatment, if necessary, then adding an alkali material to the slurry while preheating the slurry before the slurry reaches a temperature of forming scales originating from deposition of boehmite-type alumina from the slurry, thereby obtaining the slurry having an adjusted molar ratio of Na.sub.2 O/Al.sub.2 O.sub.3 of more than 1, further preheating the slurry having the adjusted molar ratio to a temperature higher than that of forming scales originating from deposition of boehmite-type alumina from the slurry before the adjustment of the molar ratio, and then extracting the alumina from the alumina-containing ores in the slurry admixed with a separately preheated alkali solution in the digester.

A restricting pin is provided so as to be slidable in a moving direction of a front end of a reverse restricting member provided at a select lever for selecting forward and reverse fork shafts switching a shift gear(s), and is biased toward the reverse restricting member. A lockout lever that can be inserted into/detached from between the restricting pin and the front end of the reverse restricting member is biased toward an insertion side by a spring, and at a vehicle speed less than a predetermined vehicle speed. A front end of an advancing operating rod of the actuator contacts and is detached against the force of the spring. At a vehicle speed not less than a predetermined vehicle speed, the front end of the reverse restricting member contacts the inserted lockout lever, thereby preventing the select lever from moving to a reverse select position.
