摘要： The invention relates to a method for purification of a cobalt containing feed solution from impurity metals by processing the feed solution through a continuous counter-current ion exchange process comprising of several beds containing cationic ion exchange material arranged in interconnectable zones 1, 2, 3 - N in a simulated counter-current moving bed arrangement, wherein each bed is interconnectable with two adjacent beds, the method comprising:
(a) introducing a desorbent solution, which has sufficiently low pH that impurity metals are desorbed, into one or more beds of the first, regeneration zone (zone I) and collecting an extract containing impurity metals from the same bed and/or from another bed downstream within the said regeneration zone,
(b) introducing a wash solution of pH higher than the desorbent solution into one or more of said beds of the regeneration zone and collecting an extract containing impurity metals and desorbent from the said bed and/or from another beds downstream within the first, regeneration zone,
(c) introducing an aqueous eluent of pH sufficiently low to desorb Co but sufficiently high not to desorb impurity metals into one or more beds of zone downstream (zone II) to said regeneration zone,
(d) introducing the cobalt containing feed solution, which has pH sufficiently high to adsorb impurity metals but sufficiently low to avoid adsorbing Co, into one or more beds of the next zone downstream (zone III) from the zone of step (c) and collecting a cobalt product raffinate solution from the said bed and/or from another beds downstream,

wherein the positions where the cobalt containing feed, eluent, desorbent, and wash solution are introduced and where the impurity metals containing extract, spent wash solution, and cobalt containing raffinate are collected are changed to adjacent beds downstream to simulate the counter-current flow of the solid and liquid phases after such periods of time that cobalt propagates downstream with fluid phase in zones II and III, impurity metals propagate upstream with the simulated flow of the solid phase in zones II and III, impurity metals are desorbed in zone I, and the desorbent is washed from the resin in zone I.

摘要： The present invention relates to a two-stage leaching process using concentrated hydrochloric acid that upgrades a variety of inferior quality titanium-iron ores into premium titanium concentrate and iron oxide products. The ground ore is leached with two separate quantities of hydrochloric acid after which the dissolved titanium is precipitated from the filtered liquor by hydrolysis. The still soluble iron chlorides are then optionally subjected to oxyhydrolysis to recover iron oxide and HCl. The process was developed for low-grade ores (under 12% TiO2), and can be naturally applied advantageously to higher grade titanium-bearing ores.

摘要： A process is disclosed for separation and recovery of vanadium, molybdenum, iron, tungsten, cobalt and nickel from alumina-based materials, mattes, ores, manufacturing by-products and waste. These elements are oxidized. The oxides are reacted with gaseous HCI to form volatile chloride- bearing compounds that subsequently sublimate. The volatile compounds are condensed in a downward-stepped thermal gradient that allows collection of moderate to high purity compounds of individual elements with exception of a nickel-cobalt co-condensate. Nickel is separated from cobalt by precipitation of nickel chloride from concentrated HCI pressurized with gaseous HCI.
