Abstract

Morowali is an industrial area engaged in metal production. Steel production is closely related to the cooling process, especially equipment cooling. In the cooling process, water is used as a cooling medium. The water used in the cooling process must be free of minerals, especially those that can damage the cooling tower equipment. Some analytical test parameters include pH, electrical conductivity, and hardness. To obtain cooling water that meets the standards, a treatment process is required. One of the treatment processes used is the ion exchange method using cation resin media, but there is a decrease in the lifetime of cation resin. One alternative material that can be used as an ion exchange medium is zeolite. Therefore, one solution that can be tried is to use a mixture of composition between cation resin and zeolite as an ion exchange medium. The research was conducted using a simple simulator tool by varying the composition of the mixture between zeolite combined with cation resin with the same initial sample and water flow rate. From the test results that have been carried out, the percent value of hardness removal for samples R100:Z100; R75:Z25; R50:Z50; R25:Z75; and R0:Z100 are 85.45%; 50.91%; 40.91%; 14.54%; 5.45%, respectively. The pH values were 7.37; 7.85; 7.80; 7.79; 7.58; 7.43, respectively. And the conductivity values are 612 "μS/cm"; 772 "μS/cm"; 719 "μS/cm"; 768 "μS/cm"; 623 "μS/cm"; 620 "μS/cm" respectively.

Abstract

One of the largest nickel producing areas in the world is Morowali, Indonesia. Stainless nickel is the raw material for battery cathodes and is also used as its precursor. In this study, Morowali laterite ore was extracted through a process known as solid-liquid extraction (leaching). Nitric acid and acetic acid solvents were used for the leaching process. The purpose of this research was to determine the effect of concentration and temperature of leaching acid solution on the percent recovery of nickel produced. Leaching was carried out with variations in concentration and temperature. In this study, the method used was acid leaching at atmospheric pressure (APAL). The results of this study indicate that increasing acid concentration and leaching temperature increases the percent recovery of nickel obtained. The best concentration and temperature from the results of this research are 7M concentration and 1100C temperature using nitric acid solvent with a nickel recovery percent obtained of 23.14% and 20.71%

Abstract

Permintaan terhadap bahan baku nikel terus meningkat seiring dengan pertumbuhan industri manufaktur, elektronik, dan baterai. Proses ekstraksi bijih nikel laterit melalui jalur hidrometalurgi, khususnya metode atmospheric leaching (AL), menghasilkan campuran padat-cair yang perlu dipisahkan melalui tahapan filtrasi. Filtrasi yang efisien dibutuhkan untuk memisahkan residu padatan dan filtrat dengan waktu proses yang singkat dan konsumsi energi minimal. Keterbatasan dari alat filtrasi konvensional seperti plate frame filter press mendorong perlunya inovasi dalam perancangan alat filtrasi yang lebih hemat energi dan mudah dioperasikan. Penelitian ini bertujuan untuk merancang dan membangun alat vertical pressure filter berbasis pompa hidrolik dengan kapasitas 600 mL yang digunakan untuk menyaring hasil ekstraksi bijih nikel laterit. Evaluasi performa alat dilakukan melalui pengujian efisiensi pemisahan padat-cair menggunakan pelarut asam sitrat. Metode yang digunakan mencakup tahap perancangan alat menggunakan perangkat lunak CAD, fabrikasi menggunakan material akrilik, besi holo, dan filter cloth 450 mesh, serta uji coba alat terhadap parameter efisiensi filtrat dan residu. Alat yang telah dibuat memiliki spesifikasi kapasitas 600 ml, pompa dengan motor hidrolik DC 12 V, pelat saringan nylon 450 mesh, gaya dorong 1000 N, dan waktu filtrasi 30 – 180 s. Dengan spesifikasi alat tersebut, hasil pengujian menunjukkan bahwa nilai efisiensi filtrat sebesar 3,76% dan efisiensi residu sebesar 76%. Ini mengindikasikan alat mampu menahan padatan dengan baik, namun filtrasi cairan belum optimal. Oleh karena itu, alat perlu disempurnakan, antara lain melalui peningkatan tekanan, pemilihan media filter yang lebih sesuai, dan optimasi waktu filtrasi untuk meningkatkan kinerja alat secara menyeluruh.
