Lithium hydroxide monohydrate production process, including the following steps: (1) lithium sulfate solution made from spodumene by roasting, acidizing, pulping, leaching and initial concentration; (2) Adding sodium hydroxide to lithium sulfate solution to obtain a mixture of sodium sulfate and lithium hydroxide solution; Li2SO4+2NaOH \u21922LiOH+Na2S O4 (3) the mixed solution of sodium sulfate and lithium hydroxide is cooled and frozen, the solution temperature is reduced to 5~-10\u2103, and sodium sulfate is separated after crystallization; (4) The clear liquid separated by freezing, heating, evaporation and concentration; (5), crystallization and centrifugal separation, lithium hydroxide crude product; (6), in the crude product lithium hydroxide solution Barium hydroxide is added to the solution to form insoluble barium sulfate, which is filtered to remove sediment and debris. The filtered solution is condensed, crystallized and separated by evaporation to obtain wet monohydrate lithium hydroxide :Ba(0H)2+S042\u2192BaS04+20H (7) Dry to lithium hydroxide monohydrate.   Lithium hydroxide monohydrate (Li0HH20)\u2026<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[84],"attr":[],"class_list":["post-741","post","type-post","status-publish","format-standard","hentry","category-problems","tag-lithium-hydroxide-monohydrate"],"_links":{"self":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/741","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/comments?post=741"}],"version-history":[{"count":4,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/741\/revisions"}],"predecessor-version":[{"id":1034,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/posts\/741\/revisions\/1034"}],"wp:attachment":[{"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/media?parent=741"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/categories?post=741"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/tags?post=741"},{"taxonomy":"attr","embeddable":true,"href":"https:\/\/www.yearnintl.com\/ko\/wp-json\/wp\/v2\/attr?post=741"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
