4 — Off‑Site Facilities & Services (Off‑Site = بیرون از خط تولید اصلی)

4.1 Off‑Site list (with priority)

1. Wastewater Treatment Plant (WWTP) — الزام اول، باید طراحی برای ZLD یا حداقل بازیافت 85–95% آب.
2. Acid Recovery & Neutralization Unit — بازگردانی HCl/HAuCl4 تا حد ممکن.
3. Slag & Solid Waste Storage (secure) — مجزا، قابل بازیافت فلزات گران‌بها و دفع امن.
4. Logistics & Bonded Warehouse — برای نگهداری شمش قبل از صادرات و امور بیمه/بانکی.
5. Security Compound / Vault — حفاظت فیزیکی و بیمه‌پذیری.
6. Energy Substation / Backup Generators — برق پایدار، ژنراتورهای دیزل + UPS.
7. Labor Accommodation (if remote) — اسکان موقت/دائمی کارگران.
8. Transport Fleet & Maintenance Hub — کامیون، لیفتراک، تعمیرگاه.

4.2 Off‑Site Flowchart — Waste & Utilities

[Acid Waste] → [Acid Recovery Unit] → [Reused Acid / Safe Disposal]
[Slag] → [Slag Treatment] → [Metal Recovery / Disposal]

نکته فنی:Zero Liquid Discharge (ZLD) یا حداقل Advanced Waste Minimization با بازیابی فلزات و بازیافت اسید.

5 — Priority Roadmap & Phased Implementation

5.1 

• Phase 0 — Pre-Investment (0–3 months): Feasibility, site visits, secure option on land, preliminary permits.
• Phase 1 — EPC & Procurement (3–9 months): Detailed design, procurement of major equipment, civil works foundation.
• Phase 2 — Construction & Commissioning (9–15 months): Installation, FAT (Factory Acceptance Test), site commissioning, pilot runs.
• Phase 3 — Ramp-Up & Optimization (15–21 months): Scale up to design throughput, AI tuning, LBMA sample prep.
• Phase 4 — Full Commercial Operation (21+ months): steady-state production, market contracts.

5.2 (Top 10 Priorities)

1. Secure feedstock supply contracts (6–12 months lock).
2. Finalize site and obtain environmental permits.
3. Procure furnace & electrolytic cells (long lead items).
4. Install WWTP and acid recovery (regulatory critical).
5. Establish QA/QC lab (LBMA sample readiness).
6. Implement AI process control & sensors (before commissioning).
7. Secure security & bonded warehouse agreements.
8. Staff hiring & training program (operators, lab techs).
9. Build investor reporting dashboards (financial & KPI).
10. Conduct LBMA pre-audit & sample submissions.

7 — Procurement & Supplier Strategy

7.1 گزینه‌های قرارداد

• EPC Turnkey Contractor — کمترین پیچیدگی مدیریت برای سرمایه‌گذار ولی هزینه بالاتر.
• Engineering + Local Build (Owner-managed) — کنترل بیشتر، CAPEX احتمالا کمتر، نیاز به تیم مهندسی.
• Modular Skids (Buy & Plug) — سریع، قابل انتقال، مناسب برای phased approach.

7.2 Long‑lead equipment (must prioritize)

• Induction furnaces, electrorefining cell stacks, filter presses, fume scrubbers, neutralization reactors, lab instruments, casting machines.

7.3 Procurement checklist

• Technical spec finalization (P&ID)
• Pre-qualification of vendors
• FAT clause in contract
• Spare parts & SLA maintenance agreement
• Local content & import duty assessment
