Mg(OH) 2 has a purity of 98.48% with a sulfur content of 0.28%. The Mg(OH) 2 was aged with a diluted NaOH solution to remove the sulfur the two-stage precipitation percentage of Mg is 96.3%. A small part of MgSO 4 coprecipitates with Mg(OH) 2 to form MgSO 4♵Mg(OH) 2♳H 2O.

H 2O to synthesize Mg(OH) 2, followed by NH 4HCO 3 precipitation to obtain 4MgCO 3.

Mg 2+ ions were first precipitated with NH 3 Ni, Co and Mn were removed by Na 2S precipitation to obtain a pure MgSO 4 solution.

Fe, Al, and Cr in the leaching solution were removed using the oxidation precipitation method with active MgO as a precipitant and H 2O 2 as an oxidant. This paper describes a leaching-purifying-precipitation process to recover magnesium from serpentine acid-leaching solution and to synthesize high purity Mg(OH) 2 and 4MgCO 3 Recognition of Reviewers: reviewers who provide timely, thorough peer-review reports receive vouchers entitling them to a discount on the APC of their next publication in any MDPI journal, in appreciation of the work done.This journal in the second half of 2022).
