Perfect Associates

Pakistan, Sindh province, Perfect Associates lists 18 active mineral products in its catalogue. The offering spans a range of industrial ores and minerals such as Fluorspar (HS 2529.21, Calcium Fluoride purity 40‑50 % to >90 %), Quartz (HS 2506.10, Silicon Dioxide 97‑99 %), Silica Sand (HS 2505.10, SiO2 95‑98 %), Magnesite (HS 2519.10, MgO 43‑50 %), Gypsum (HS 2836.50, Calcium Carbonate 80‑95 % purity), Calcium Carbonate (HS 2508.40, 45‑98 % purity), Antimony Ore (HS 2617.10, Stibnite Sb2S3) and Barite (HS 2511.10, Barium Sulfate). Additional entries include Laterite Iron Ore (HS 2601.12, Fe 35‑40 %), Limestone, Dolomite (HS 2518.10, CaMg(CO3)2), Talc/Soapstone (HS 2526.20, Hydrous Magnesium Silicate), Calcite (HS 2517.49, CaCO3 with CaO ≥50.5 %), Manganese Ore (HS 2602.00, Mn 28‑35 %) and Rock Phosphate (HS 2510.20, Calcium Phosphate).

The catalogue groups the items under broader headings such as Other Ores & Minerals, Himalayan Salt and related salts, but the HS‑code families show that the primary export focus is on non‑ferrous industrial minerals used in metallurgy, chemicals, construction and electronics. Each product entry specifies the typical chemical composition range, allowing buyers to match specifications directly to their processing requirements.

The listed minerals correspond to well‑defined industry grades. Fluorspar is commonly sold in acid grade (> 80 % F) for hydrofluoric acid production and in metallurgical grade (60‑70 % F) for steelmaking; the catalogue’s 40‑50 % to >90 % purity range covers both. Quartz with 97‑99 % SiO2 is suitable for glass and semiconductor wafer feedstock, while higher‑purity (> 99.5 %) grades are required for photovoltaic cells. Silica sand at 95‑98 % SiO2 is typically sized 0.1 - 0.5 mm for foundry molds and hydraulic fracturing, with moisture limits below 0.5 %. Gypsum lumps of 80‑95 % CaCO3 are used for plasterboard and cement additives, whereas calcium carbonate 45‑98 % serves as filler in plastics and paints; industrial users often request the 95‑99 % grade for pigment applications. Antimony ore (Stibnite) is a standard source for antimony metal, with typical impurity limits on arsenic and lead. Barite oil‑grade (BaSO4) meets the density requirements (≈ 4.2 g/cm³) for drilling fluids. These grades align with the specifications commonly found in global procurement standards for each mineral.
