Abstract

Non-destructive testing(NDT)  adalah pengujian material untuk menentukan kualitas dan integritas material atau elemen struktur tanpa memengaruhi kemampuan untuk menjalannya fungsinya. NDT itu sendiri memiliki beberapa metode pengujian, yaitu radiograph testing, eddy current testing, thermal testing, penetrant testing, ultrasonic testing, dan visual testing. Metode eddy curent biasanya digunakan untuk melihat crack maupun mengetahui perbedaan suatu material melalui nilai konduktivitasnya. Pada penelitian ini dimaksudkan untuk menanalisis dari teori yang ada dengan yang terjadi dilapangan, dengan menambahkan variasi ketebalan pada Aluminium clad sheet 2024. Cladding test sangat umum dilakukan di industri aviasi untuk menghindari, mengetahui lebih awal dan menanggulangi kecelakaan yang diakibatkan korosi karena cladding sudah hilang.

Abstract

The tailings slurry used in this research originated from company X in Kuala Lipis, Pahang, Malaysia. The primary objective of this study is to determine the percentage of recovery, concentrate content, and Au concentration ratio in the tailings slurry. The research employs a quantitative method involving flotation testing. The flotation process involved two sets of experiments: one without the FX2 collector (tests 1 and 2) and another using both the F7042W and FX2 collectors (tests 3 and 4). dxThe research findings revealed that the percentage of Au recovery in single-collector flotation using FX2 (test 1) was 56.47%, with a concentration ratio of 19.78. In test 2, it was 52.59%, with a mass concentration ratio of 21.57. Meanwhile, the percentage of Au recovery in dual-collector flotation using F7042W and FX2 (test 3) was 68.77%, with a concentration ratio of 16.55, and in test 4, it was 69.45%, with a concentration ratio of 16.93. Based on the results of this research, it can be concluded that the flotation process employing two collectors, namely F7042W and FX2, as investigated in this study, was successful because percent recovery, concentration ratio, and Au content in the concentrate compared to single collector flotation.
