Minbos Resources Updates Cabinda Phosphate Definitive Feasibility Study


Due to the high potential local demand for raw phosphate rock (PR), Minbos Resources has decided to include new plant configurations to capture current market opportunities in the Definitive Feasibility Study (DFS) for the Cabinda phosphate in Angola.

Fertilizer prices have hit new records as global supplies are hit by multiple factors, including war in Ukraine, Chinese fertilizer export bans and supply chain inflation, with prices for raw materials that make up processed fertilizers – ammonia, potash, phosphates, sulfur – up 30% since the start of the year.

Globally, phosphate markets are booming, propelled by buyers’ fears that a major disruption in global ammonia supply could, in the short term, lead to cuts in DAP and MAP production . More importantly, supply constraints are accentuated in small markets, with Angolan consumers and importers unable to source MAP and DAP at any price.

MAP and PR are the key ingredients in Cabinda Phosphate Granules. Although the company’s PR is still available at cost, at current prices, MAP would represent approximately 90% of the cost of raw material input costs for pellets, which would have a large and disproportionate impact on the price of pellets. products.

Minbos and the International Fertilizer Development Center (IFDC) are now planning a role for the company’s enriched PR to be used in the Angola Farm and Fertilizer Productivity Program (AFFPP).

Minbos was recently approached by mega-farms and regional distributors, representing over 60,000 hectares, regarding the availability of Enriched Cabinda Phosphate Rock (CPR).

Preliminary analysis using a Phosphate Rock Decision Support System (PRDSS) demonstrated that CPR could be a viable source of nutrients for the majority of new agricultural projects in Angola and, more importantly still, a competitive cost in today’s market.

Field trials in Angola over the past three seasons have compared Cabinda pellets to MAP and CPR, demonstrating the effectiveness of CPR for staple crops like beans and in some trials even outperforming MAP. The company has received numerous inquiries for its CPR from exporters, importers and customers interested in enriched and crude PRs.

The granulation flow sheet has been designed to be flexible and allow the production of different products and formulations. An external review of the flowsheet by IFDC concluded that the current plant is capable of producing fortified PR products with minor modifications. The mass and energy balances can be simply calculated and will be verified during a pilot plant test scheduled for early June.

Updating the DFS requires updating the production scheme which can be reused to switch from granulation to PR recovery campaigns with relatively minor changes.

Engineering calculations will be completed in the coming weeks and will be confirmed during the next pilot test scheduled for the second week of June at IFDC headquarters. This trial will produce 7 t of product for agronomic demonstration trials in Angola later this year. The engineering component of the revised DFS can be completed in approximately 3 months and the company will provide an update on the market component after technical discussions with potential new customers. Meanwhile, the company will continue the construction of its phosphate plant through its EPCM subcontractors.

CEO Lindsay Reed said: “It has been a remarkable few weeks and months for Minbos with seemingly limitless new business opportunities arising. What is clear, however, is that the local appetite for our phosphate is both real and significant.

Since the company was completing a DFS that produced a blend of MAP and phosphate rock fertilizer, we made the decision to expand the scope of the DFS to include both blended fertilizers and enriched phosphate rock.

The Company is confident that it can achieve similar efficiencies, reduce working capital requirements, reduce customer expenses and potentially accelerate the full plant utilization schedule, all without delaying plant commissioning. ‘plant.

We look forward to finalizing the DFS which, if implemented, will provide greater food security to Angola and the wider Central African region.
