N2  - Dalam penelitian ini, dilakukan proses proses perolehan seng sulfat (Zn   
) dari 
hasil larutan pelindian buatan menggunakan metode kristalisasi anti pelarut (anti 
solvent crystallization). Pengaruh beberapa parameter yaitu konsentrasi awal seng 
dalam larutan hasil pelindian, penambahan reagen anti pelarut (metanol, etanol 
dan aseton) dan pengaruh ion sejenis terhadap efisiensi kristalisasi seng sulfat 
akan dipelajari menggunakan metode batch. Hasil penelitian menunjukkan bahwa 
persen perolehan akan meningkat dengan meningkatnya konsentrasi seng awal, 
persen perolehan tertinggi diperoleh pada konsentrasi awal seng 1 M yaitu 
96,96%. Penambahan reagen anti pelarut menunjukkan hasil yang positif yaitu 
perolehan meningkat dengan meningkatnya rasio volume reagen:larutan 
pelindian, persen perolehan tertinggi diperoleh pada rasio volume 1:9 sebesar 
99,52% (etanol) dan 103,22% (aseton). Penambahan ammonium sulfat sebagai 
ion sejenis mempengaruhi peningkatan persen perolehan dengan nilai tertinggi 
yaitu sebesar 99,99%. Sedangkan penambahan asam sulfat menghasilkan persen 
perolehan yang jauh lebih rendah (10,41%) dibandingkan dengan penambahan 
ammonium sulfat. Hasil karakterisasi SEM menegaskan bahwa seng dalam 
larutan pelindian buatan berhasil dikristalisasi sebagai seng sulfat.

In this study, the process of obtaining zinc sulfate (ZnS  ) from the results of 
artificial leaching solution was carried out using the anti-solvent crystallization 
method. The effect of several parameters, namely the initial concentration of zinc 
in the leaching solution, the addition of anti-solvent reagents (methanol, ethanol 
and acetone), and the effect of similar ions on the efficiency of zinc sulfate 
crystallization will be studied using the batch method. The results showed that the 
percent gain will increase with increasing initial zinc concentration, the highest 
percent recovery is obtained at the initial zinc concentration of 1 M which is 
96.96%. The addition of anti-solvent reagents showed positive results, namely the 
gain increased with increasing volume ratio of reagent:leaching solution, the 
highest percent recovery was obtained at a volume ratio of 1:9 of 99.52% 
(ethanol) and 103.22% (acetone). The addition of ammonium sulfate as a similar 
ion affects the increase in percent recovery with the highest value of 99.99%. 
While the addition of sulfuric acid resulted in a much lower percent recovery 
(10.41%) compared to the addition of ammonium sulfate. The SEM 
characterization results confirmed that zinc in artificial leaching solutions was 
successfully crystallized as zinc sulfate.
