Abstract
Lithium merupakan suatu mineral yang banyak digunakan pada
pembuatan baterai yang dapat di isi ulang (rechargeable).Pada
penelitian ini dilakukan proses ekstraksi Lithium melalui metode
Hydrometallurgi dengan variasi penambahan NaOH untuk
mengetahui pengaruhnya terhadap efisiensi pada proses
ekstraksi. Penambahan NaOH di lakukan dengan variasi NaOH
0.1 M, NaOH 0.3 M dan NaOH 0.5M. Proses penambahan ini
dilakukan dengan pencampuran variasi penambahan NaOH
sebanyak 200ml dan lumpur kering Sidoarjo yang memiliki
ukuran 80 μm. Setelah proses pencampuran hingga menjadi
slurry, slurry dipanaskan pada temperatur 85oC selama 1 jam.
Dari pengujian XRD menunjukkan terbentuknya Li2CO3 dengan
intensitas tertinggi yaitu pada peak posisi 2θ 45.7912
intensitasnya 1000 pada NaOH 0.5M. Pada pengujian SEM,
terlihat Li2CO3 terindikasi berbentuk kubus. Namun pada
pengujian ICP terjadi penurunan efisiensi dengan efisiensi
terkecil sebesar 26.9% pada penambahan NaOH 0.5 M dan
efisiensi terbesar sebesar 35.3% pada penambahan NaOH 0.1M.
===========================================================
Lithium is a mineral used in the manufacture of rechargeable
batteries. On the research of Lithium extraction process is done
through the Hydrometallurgi method with the addition of NaOH
to know its effect on efficiency in the extraction process. The
addition of NaOH in done with variation of NaOH 0.1 M, NaOH
0.3 M and NaOH 0.5 M. This process is done by mixing
variations of the addition of as many as 200 ml of NaOH and
Dried lumpur Sidoarjo that has a size of 80 μm. After mixing
become a slurry, slurry is heated at a temperature of 85oC for 1
hour. From testing XRD showed the formation of Li2CO3 with the
highest intensity at peak position 2θ 45.7912 which intensity 1000
in 0.5 M NaOH. On testing SEM, There is Li2CO3 who looks like
cube. However on testing ICP occurs a decrease in efficiency
with the smallest efficiency of 26.9% in addition of NaOH 0.3 M
and the largest efficiency amounting to 21.9% in addition of
NaOH 0.1 M.
