Abstract

Batubara merupakan bahan galian yang strategis dan salah satu bahan energi nasional yang mempunyai peran besar dalam pembangunan nasonal.Tujuan dari penelitian adalah untukmengetahui jumlah persentase kandungan sulfur dalam batubara dan dampak kandungan sulfur terhadap pemanfaatannya dalam bidang industri. Adapun metode yang digunakan dalam pengambilan data yaitu dengan melakukan preparasi sampel dengan cara penimbangan, penggilingan, pencampuran, pengeringan dan milling, setelah itu dianalisis Furnace  TS untuk mendapatkan persentase kadar sulfur dari sampel tersebut. Persentase kadar sulfur dari lima sampel yang dianalisis yaitu sampel B1 memiliki kadar sulfur 1,56%, sampel B2 memiliki kadar sulfur 1,16%, sampel B3 memiliki kadar sulfur 1,23%, sampel B4 memiliki kadar sulfur 1,43%, dan sampel B5 memiliki kadar sulfur 1,36%. Maka dari kelima sampel tersebut di dapatkan nilai rata-rata yaitu 1,34%. Dari kelima sampel yang diteliti dengan rata-rata kandungan kadar sulfur 1,34% tidak layak untuk digunakan dalam bidang industri pabrik semen karena melebihi parameter yang dibutuhkan yaitu maksimal 0,80%, dan begitupun penggunaanya dalam industri PLTU karena total sulfurnya melebihi parameter kebutuhan yaitu maksimal 0,40%.

Abstract

One of Indonesia’s potential gold ore deposits is found in the Bolaang Mongondow area of North Sulawesi Province. This research is one of the initial studies conducted to determine the metal content of gold in ore deposits based on the results of Au extraction using aqua regia. It is known that several operating parameters determine the success rate of the leaching process. One of these parameters is the leaching time. The leaching time ranges used in the study were 5, 10, 20, 60, and 120 minutes. Based on the variation of the leaching time applied to the leaching process, it will also be known how much mass of dissolved Au metal is. The leached filtrate obtained was then analyzed for its concentration using AAS (Atomic Absorption Spectrometry) instrument. The AAS data were then processed using x and y curves to obtain the optimum leaching time, and the mass of dissolved Au metal was obtained using the equation. The results showed that the optimal time for the hydrometallurgical process in gold ore deposits was 120 minutes with an Au concentration of 1.67 mg/L.
