This study investigates the process of extracting tungsten from used hydrocracking catalyst (specifically model 102-HC W/Ni/Al2O3, SiO2), and provides valuable insights into efficient recycling secondary sources. Tungsten samples are isolated with sodium hydroxide(NaOH, caustic soda or lye) then analyzed using X-ray fluorescence (XRF) methods. The main components sample lithium-aluminum-tungsten-oxide (LiAIW2O4), nickel-molybdenum oxide (NiMoO4), (WO3), silicon (SiO2). experimental design focuses on parameters such as roasting temperature, time, pulp density, leaching time during preparation operation. temperature have a combined effect extraction, being factor. Increasing density reduces longer hydroxide improves recovery. Under conditions 800 °C, 120 min, 10 %, 70 60 dissolution recovery rate is 92.3 %.

In road engineering, construction requires a large amount of natural aggregate; its substitution with recycled construction-solid-waste aggregate not only saves resources but also reduces the burden on environment. The main components solid waste are concrete blocks and brick slag; breakability latter can affect performance mixed aggregate, which hinders use in engineering applications. To analyze applicability containing slag subgrade layer, effect content CBR (California bearing ratio) crushing value aggregates was evaluated based laboratory tests, field compaction quality analyzed. results show that 9.5–19 mm samples were crushed to higher degree during process. A less than 40% had little aggregate. It is recommended 22 t roller for five passes (two weak vibrations + two strong one vibration) at speed 3 km/h stage filling.
