1. ABERTURA ACIONADA POR PAINPOINT

Establishing and operating a quarry site in Lagos presents distinct regulatory and operational hurdles. Navigating the complex approval process with the Federal Ministry of Mines and Steel Development (FMMSD) and other agencies is just the first step. Once operational, sites face persistent challenges: inconsistent aggregate quality from variable local geology leading to product rejection, excessive downtime from equipment unsuitable for lateritic soils and hard rock transitions, and severe pressure to control operational costs amidst rising fuel prices and logistics constraints. Are you managing site planning delays due to uncertain mineral deposit assessments? Are you experiencing profit erosion from low plant availability and high maintenance cycles? The foundation of a profitable, compliant operation begins with a professionally engineered design service tailored specifically for FDA approved quarry sites in Lagos.

2. VISÃO GERAL DO PRODUTO

Nosso serviço é abrangente Quarry Site Design and Engineering Package for greenfield or brownfield expansions targeting limestone, granito, or laterite extraction in SouthWest Nigeria. This is not just a site plan; it is an integrated operational blueprint. The workflow begins with (1) Geotechnical & Análise de Reserva of your licensed acreage to precisely define ore body geometry and quality. This feeds into (2) Process Flow & Plant Layout Design, optimizing material movement from face to crusher to stockpile. The third phase (3) Infraestrutura & Compliance Engineering details haul roads, drenagem, sedimentation ponds, and power distribution to meet all regulatory stipulations for an FDA approved quarry site. This service is applicable for operations targeting 100 1,000+ TPH capacity but requires clientprovided core drilling data and a valid mining lease as foundational inputs.

6. CENÁRIOS DE APLICAÇÃO

Granite Quarry Expansion in Ogun State

Challenge A longestablished quarry faced depletion of its initial pit. The operator needed to expand into adjacent leased land while maintaining uninterrupted production from the existing plant.
Solution Our design service conducted a new reserve assessment on the new acreage and engineered a phased haul road network that connected new faces directly into the existing primary crusher feed hopper.
Results The operator avoided a complete plant relocation. The expansion was executed without stopping existing production lines within one fiscal year.

New Greenfield Limestone Quarry

Challenge An investor with an FDAapproved mining lease required a bankable feasibility study layout that would secure financing.
Solution We provided a complete quarry site design package focused on minimizing initial capex through modular staging while demonstrating clear pathways to fullscale production.
Results The detailed engineering reports satisfied lender requirements. The optimized layout reduced estimated initial earthworks costs by approximately NGN45 million.
