Supporting Indonesia's Gold Mining, Solving Slurry Transportation Challenges with Professional Pumps - The Win-Win Cooperation Between XINGOU Slurry Pumps and an Indonesian Gold Mine

A medium-to-large gold mine in Papua Province (Indonesia’s core gold-producing area) engages in mining, grinding and cyanide leaching, with slurry transportation as a key link in its whole-slime cyanidation CIP process. One year ago, persistent slurry pump failures disrupted production—until it partnered with us. This cross-border cooperation, based on real conditions and scientific solutions, solved its dilemmas and achieved win-win results.

The mine faced specific challenges: post-grinding ore slurry had over 90% fine particles (< 0.074mm), solid content fluctuating 14%-45%, slightly alkaline slurry (pH 7.0-11.0) with weak corrosiveness, and a hot, humid tropical climate (26-32℃, frequent rain) damaging electrical components. Its original pumps failed often: flow parts needed replacement every 1.2-1.5 months, seals leaked, 5-7 monthly unplanned shutdowns cut efficiency by 15%, causing $75,000 monthly losses. Parameter adjustments and spare part replacements failed to resolve the issue.

We dispatched 2 senior mining slurry engineers (10+ years of gold mine experience) for a 7-day on-site investigation, collecting 900+ key data sets (concentration, particle size, pH, pressure). By analyzing faulty pumps, we identified root causes: insufficiently wear-resistant original materials (HRC 58-60), non-corrosion/moisture-resistant seals, unoptimized hydraulic models for variable concentration slurry, and lack of pump moisture protection.

We designed a targeted, practical customized solution: flow parts used Cr28Ni4Mo2 alloy (surface-hardened to HRC 65-68), extending service life to over 12 months; a corrosion/moisture-resistant seal system (modified PTFE + silicon carbide) and moisture-proof cover solved leakage and electrical damage; optimized hydraulic models with wide-channel closed impellers improved variable concentration adaptability, boosting efficiency to 79% (10% energy savings); a simple monitoring module displayed real-time parameters for easy maintenance.

We strictly followed ISO standards in production, conducting 72-hour full-load tests to simulate the mine’s working conditions before shipment. We strengthened packaging for long-distance transportation and pre-formulated a detailed installation plan to match the mine’s cyanidation process, minimizing installation time.

Our on-site service ensured smooth cooperation: the team completed installation/commissioning in 3 days, provided 7-day training for the mine’s staff on operation, maintenance and fault handling, and stayed 3 extra days to adjust parameters and ensure stable initial operation.

We established a targeted after-sales mechanism: 24-hour online support (≤2-hour response) and on-site service within 72 hours via local partners. When a slurry concentration surge occurred, we resolved it in 5 hours through remote guidance and on-site adjustment, minimizing losses.

Our pumps have operated stably for over a year, with practical results: 88% fewer unplanned shutdowns (≤1 monthly), 8x longer flow part service life, 25% higher transportation efficiency, 3% improved leaching efficiency, and $850,000+ annual cost savings (250% ROI). They adapt well to fluctuating solid content (±5%) and pH (7.0-11.0), winning the mine’s recognition.

This cooperation reflects our "real conditions, scientific solutions" concept. The mine is now our key Southeast Asia customer, recommending us to other gold mines in Papua and Sulawesi, laying a foundation for market expansion in Indonesia.

With years of experience, we provide scientific, cost-effective slurry solutions for global gold mines, adapting to regional conditions and creating practical value through professionalism.
