Abstract
Proses pengolahan timah menghasilkan produk samping yang disebut slag. Slag merupakan campuran mineral yang masih mengandung timah sekitar 4 hingga 20 persen. Pemisahan timah dilakukan dengan melarutkan slag ke dalam HCl sehingga didapatkan larutan ekstrak yang mengandung timah dalam bentuk stannate chloride (SnCl4). Proses ekstraksi dilakukan dengan variabel tetap yaitu massa slag timah dan kecepatan pengadukan, sedangkan variabel berubahnya adalah ukuran partikel, konsentrasi pelarut dan rasio liquid/solid. Kemudian menganalisa kandungan timah dalam ekstrak sehingga hasil analisa dapat digunakan dalam menentukan persen recovery timah. Dari penelitian ini, didapatkan bahwa semakin kecil ukuran partikel slag (100 – 150 mesh) dan semakin besar ratio perbandingan HCl/slag (6/1 – 25/1) akan meningkatkan persen recovery timah pada temperatur 80°C dengan kecepatan pengaduk 900 rpm. Persen (%) recovery tertinggi 60,85% didapat pada ukuran slag 150 mesh (0,099 mm) dengan waktu proses 20 menit, dan rasio HCl 10%wt / slag = 25 / 1.

Tin treatment process produces byproducts called slag. Slag is a mixture of minerals containing lead is still about 4 to 20 percent. Separation is done by dissolving tin slag into HCl to obtain a solution containing extracts in the form of stannate tin chloride (SnCl4). Ffixed variable are the tin slag mass and the speed of stirring, while the modification variables are the particle size, solvent concentration and the ratio of liquid / solid. Then analyze the lead content in the extract so that the results of the analysis can be used to determine the percent recovery of lead. From this study, it was found that the smaller the particle size of the slag (100-150 mesh) and the greater the ratio ratio HCl / slag (6/1 - 25/1) will increase the percent recovery of lead at temperature of 80 ° C with a stirrer speed of 900 rpm. Highest percent (%) recovery 60.85% obtained by slag size of 150 mesh (0.099 mm) with a process time of 20 minutes, and the ratio of HCl 10% wt / slag = 25/1.
