Abstract

Recycling lithium batteries (LIB) has emerged as an attractive solution in the global pursuit of environmentally friendly practices. The aim of achieving zero–waste hydrometallurgical technology is within reach. This research focuses on utilizing the low-pressure nanofiltration process to address this challenge by separating lithium ions from other ions and achieving a desirable permeate flux. The NCA battery leachate concentrate was obtained through a hydrometallurgical process involving sulfuric acid–peroxide. To ensure the prevention of potential nanofiltration membrane (TS80) fouling, the concentrate is initially filtered using an ultrafiltration membrane (UH004) to remove any particles. The research investigates the impact of pressure (4, 6, and 7 bar), solution concentration (concentrate, 10x, and 50x dilution), and the concentration of the complexing agent (EDTA) on the desired separation performance. The investigation reveals that pressure variations exhibit consistent rejection rates, remaining stable above 80%. A similar trend is observed with the addition of EDTA, which consistently yields rejection rates above 80%. However, when examining different feed concentrations, the rejection of lithium falls below 80% for leachate concentrates. In summary, satisfactory results are obtained by employing nanofiltration with a TS80 membrane at a pressure of 7 bar, a dilution factor of 10x, and using a 0.02M EDTA complexing agent. Meanwhile, it was found that the separation factors (Li⁺/Ni²⁺ = ~8.6, Li⁺/ Co²⁺ = ~7.3, Li⁺/Al³⁺ = ~4.9) and permeate flux ±46.58 L m⁻² h⁻¹. The findings demonstrate good selectivity along with relatively high flux.

Abstract

In the process of flotation of copper-bearing ore, several factors such as the concentration of the collector used and the pH of the fluid used can have an impact. In this study, observations were made on the influence of collector concentration and pH on the recovery of copper ores from Papua, Indonesia. The ore samples were obtained from three different site. Preparation of samples were conducted by crushing and sieving to obtain solid particles with a size of +200 mesh. The fine particles then fed into froth flotation device. Froth flotation operations were carried out at different operating condition namely pH (pH 3, pH 6, and pH 9), xanthate concentration (1300, 2000, and 2600 ppm), and time (3, 5, 7, and 14 minutes). The froth and tailings were collected separately and dried in an oven at 60oC. The feed, froth, and tailings were then subjected to EDX analysis to determine their compositions. The results of the experiment showed that higher collector concentrations did not necessarily lead to increased copper recovery. The appropriate pH conditions, however, could optimize copper recovery. The optimum conditions obtained from this experiment were xanthate concentration of 2000 ppm, pH of 3, and the ore sample 2

Abstract

The increasing price and the decreasing stock of fossil fuel nowadays are two factorsthat make the use of alternative fuel with lower price become necessity. The source ofenergy that can be used to fill the gap between convensional fossil fuel towards cleanerand renewable energy is Coal. South Banten has a massive stock of coal, around 70% ofall the mineral sources in South Banten, but the quality of the coal is low, due to thesulfur content around 2.28 % dry basis and a high water content that lead to the lowestcalor content. The aim of this research is to lowering the sulfur and water content ofthe coal. Upgrading Brown Coal methode is the methode used to reach the aim stated.The research was settle at temperature 150: C, pressure 350 kPa, and addition ofkerosene as the solvent. The result of the research shows the increasing of calorcontent and the decreasing sulfur content when the evaporation temperature graduallyincreased.

Abstract

Industrial water consumption will account for 22% of global water demand by 2030. Industry water conservation is encouraged by rapid corporate growth. Industrial resource usage and pollutant emissions can be reduced via cleaner production methods. Recycling is essential to greener production and the circular economy. Recycling is crucial to achieving the 2030 Sustainable Development Goals. The electric vehicle (EV) sector has propelled battery business growth in recent years, especially in Indonesia. The electric vehicle (EV) sector will benefit from using Nickel Manganese Cobalt (NMC) batteries. The study will use reverse osmosis (RO) membrane filtration to recover water from recovered NMC battery effluent. The experiment will investigate feed solution concentrations, pressures (8, 10, and 12 bar), and temperatures (30, 40, and 50°C). Two factors—permeate flux and metal ion rejection—determine reverse osmosis membrane efficiency. Li and Na metal rejection was maximum at 30°C and 12 bar, with 94-96% and 90-93% rejection rates, respectively. Under certain operating conditions, reverse osmosis membrane technology significantly reduced sodium (Na) concentration in NMC battery recycling effluent. Thus, wastewater is no longer saline. Reverse osmosis water can be reused for cooling due to its Li and Na concentrations.
