Middle Grade Magnesite is a caustic calcined magnesite with a magnesium oxide content exceeding 95 wt %, produced by high‑temperature sintering in shaft kilns. The material is supplied by Dalian Lm Mining Co., Ltd. and is commonly shipped as dense lumps or briquettes. The listing notes that the product is suitable for refractory brick manufacture, steelmaking, cement production and glass melting processes. No specific bulk density or moisture content is provided, so those figures should be confirmed with the supplier.
In the refractory industry, magnesite of this grade typically contains silicon dioxide around 2‑3 wt % and calcium oxide between 1‑2 wt %, which helps control melt viscosity and improve slag resistance. Bulk density for middle‑grade magnesite usually falls in the range of 1.8‑2.0 g cm‑3, and grain sizes are supplied between 0 and 30 mm to suit various moulding techniques. The material is often packaged in jumbo bags of up to one tonne or in bulk containers for sea freight, a practice that reduces handling costs. These typical parameters align with the specifications described in ASTM C618 for magnesite used in high‑temperature applications.
Primary customers include refractory manufacturers, steel mills and cement producers who require consistent MgO purity and thermal stability. The product is shipped from Dalian, Liaoning, China, and buyers should verify the exact moisture level, bulk density and particle‑size distribution before finalising a contract. Because the listing does not disclose minimum order quantity, lead‑time or payment conditions, importers are advised to obtain those details directly from Dalian Lm Mining Co., Ltd. prior to placing an order.

The listing does not provide details on annual production capacity, certification status or export experience, so buyers should request any additional information directly from the supplier.
Middle Grade Magnesite is a caustic calcined magnesite with MgO content above 95%, processed through briquetting and high-temperature sintering in shaft kilns. It serves critical applications in refractory brick manufacturing, steelmaking, cement production, and glass industries where high thermal resistance is required. As a globally traded industrial mineral, it is typically supplied in lump or graded form with packaging in jumbo bags or bulk containers for efficient freight and handling.

Importers should first request a recent assay report confirming MgO, SiO2 and CaO levels, as well as a moisture analysis. Verifying the bulk density and grain‑size distribution against the supplier’s data helps avoid surprises during container loading and refractory production. It is also prudent to ask for a Material Safety Data Sheet and any relevant export certifications before finalising the purchase.
Logistics for magnesite typically involve sea freight in bulk containers or jumbo bags, with the choice of Incoterm negotiated between buyer and supplier. Lead times can vary depending on port congestion and seasonal demand, so the buyer should obtain a realistic shipping schedule from Dalian Lm Mining Co., Ltd. Payment terms are not listed, and a secure method such as a confirmed Letter of Credit is advisable for first‑time transactions.
During the sourcing process, arrange for a third‑party inspection to confirm that the delivered material matches the agreed specifications, especially MgO purity and moisture content. Request a Certificate of Analysis for each shipment and retain the inspection report for customs clearance. Proper documentation ensures compliance with both Chinese export regulations and the buyer’s downstream quality requirements.
