Silica (SiO₂) is the second most abundant mineral on Earth, composed of silicon and oxygen. Industrial applications require high purity, typically above 98% SiO₂. Silica sand, a fine form of quartz with at least 95% SiO₂ and low iron content, is used in glassmaking, construction, metal casting, oil and gas drilling, and chemical production.

Coal is a high-demand natural resource used globally across various industrial sectors. Our coal is a premium-grade product derived from select mining operations in Indonesia, known for its high calorific value, low ash, and low sulfur content — qualities that meet the stringent requirements of international markets. We offer coal in various grades, including sub-bituminous and bituminous types, suitable for thermal power generation, cement manufacturing, and metallurgical processes such as coke production. With consistent quality and reliable supply capacity, our coal is an ideal energy solution for global partners seeking efficient and environmentally compliant fuel sources.

Nickel is a versatile transition metal known for its high corrosion resistance, strength, and ability to withstand extreme temperatures. Typically sourced from laterite and sulfide ores, industrial-grade nickel (purity ≥ 99%) is a key component in stainless steel production, battery manufacturing (especially for electric vehicles), electroplating, and superalloys used in aerospace and power generation. With its excellent thermal and electrical conductivity, nickel plays a crucial role in energy storage and sustainable technologies.
