翻译: Frequently Asked Questions
铬精矿主要适用于哪些高要求工业领域？
高品位铬精矿（48-52% Cr2O3，超低二氧化硅）专用于：1）钢铁高温熔炉及水泥回转窑镁铬耐火砖制造；2）重型铸造行业耐热抗热震专用铬铁矿砂；3）重铬酸钠及铬酐等高端铬化工合成原料。
巴基斯坦铬精矿如何进行选矿与质量监控？
原矿石经多段球磨、水力分级及重力摇床物理选矿剔除脉石，不添加有害浮选药剂。装箱前由SGS或AHK在卡拉奇港完成取样、XRF多元素化验及烘干水分测定，出具独立商检证明。
Can international buyers enter into forward off-take agreements?
Yes. With our KPK beneficiation facility currently under active commissioning, we welcome advance off-take discussions, technical specification alignment, and forward volume contracts with international ferrochrome smelters and industrial alloy producers.
What industrial applications require chromite concentrate rather than lumpy ore?
Chromite concentrate (0-1mm sand) is predominantly required by: 1) High-carbon ferrochrome (HC FeCr) and charge chrome smelters seeking uniform high-recovery charge material, 2) Refractory brick manufacturers producing high-temperature magnesia-chromite bricks for steel furnaces, and 3) Chemical producers synthesizing sodium dichromate.
What packaging is used to prevent moisture contamination and bag tears?
We package chromite concentrate in premium 1.25 to 1.5 MT UV-stabilized woven polypropylene Big Bags (FIBCs) featuring four heavy-duty lifting loops and internal polyethylene moisture barrier liners, securely stuffed in 20ft shipping containers.

Why Pakistani Muslim Bagh Chromite Smelts Faster
High Cr:Fe Ratio (2.8:1 - 3.1:1 min): Minimizes iron dilution in the molten bath, allowing stainless steel and ferrochrome producers to achieve higher chromium recovery with lower electrical power consumption per ton.
Negligible Trace Harmfuls: With Phosphorus restricted below 0.005% and Sulfur below 0.010%, Pakistani chromite eliminates the risk of hot-shortness and brittle defects in high-tensile austenitic stainless steels.
Natural High Refractoriness: Balanced MgO and Al₂O₃ content yields refractory bonding suitable for cement rotary kiln linings and ladles up to 1,750°C.

Product Selection Guide
Comparing Lumpy Chromite Ore vs. Beneficiated Chromite Concentrate
Choosing between lump ore and fine concentrate depends on furnace design, reduction technology, and end-product chemistry.
| Feature | Metallurgical Lumpy Ore | Beneficiated Concentrate |
|---|---|---|
| Physical Form | Hard, dense irregular lumps (10mm - 150mm) | Fine, crystalline black sand (0mm - 1.0mm, AFS 45-55) |
| Cr₂O₃ Purity Range | 30% to 42%+ (Run-of-mine hand sorted) | 48% to 52%+ (Gravity separated) |
| Silica (SiO₂) Level | 8.0% - 12.0% max (Natural gangue) | Ultra-Low (3.5% - 6.0% max) |
| Primary Industrial Applications | Submerged Arc Furnaces (SAF) for High-Carbon Ferrochrome (HC FeCr), charge chrome, and direct stainless steel smelting without agglomeration. | Direct feedstock for Refractory Magnesite-Chrome bricks, foundry casting sands, chemical synthesis (Sodium Dichromate), and pelletized ferrochrome. |
| Handling & Container Stuffing | Loaded loose in lined 20ft containers (27-28 MT/FCL) or heavy jumbo bags. | Exported in 1.25 - 1.5 MT UV-stabilized Big Bags with internal moisture barrier liners. |
