Abstract

The retreatment process is a method used to convert waste into something economically
valuable and useful. Tin tailings from the Mineral Processing Division (BPM) accumulate in the
tailings dump and still have the potential to contain tin which can be retreated to get tin minerals
back. The retreatment process uses a concentration process with a shaking table. This research
method uses quantitative methods through literature studies and field approaches using experimental
data. The purpose of this study is to determine the distribution of tin in BPM tin tailings and analyze
the effect of deck slope and water flow velocity on tin content and recovery.
The feed used in this research is the tin tailings from BPM. The variations of deck slope used
are 1°, 1.5°, and 2°, and the flow rates of water used are 12.2 L/minute, 20.7 L/minute, and 24.9
L/minute. Initial feed and concentrate concentration analysis were performed using X-Ray
Fluorescence (XRF). To achieve the highest concentrate grade, a combination of a 2° deck slope and
a water flow rate of 24.9 L/minute with a grade of 56.79% was used. Meanwhile, the highest
recovery was obtained using a combination of a 1° deck slope and a water flow rate of 12.2 L/minute
with a recovery of 46.83%. To achieve high grade and recovery, a combination of deck slope and
water flow rate is required.
