Minerals Processing in Brazil

The services provided by Pöyry in Minerals Processing encompasses all stages of the value chain from exploration through implementation and operation of a steel mill, smelter, refinery, plant of fertilizers, cement, glass and ceramics.

Mining

Ore extraction

• Open-pit mine
• Underground mine

Minerals processing

Ore beneficiation

• Industrial minerals
• Metal bearing minerals

Transformation processing

• Non-ferrous
• Ferrous
• Iron & steel
• Stainless steel
• Fertilizers
• Cement
• Glass and ceramics

A differentiation factor to highlight in Pöyry is the integrated view of the project, starting with the design of investment up to its implementation and management. In many cases, we follow our customers during the operation, supporting them in plant engineering, energy efficiency increase and operational improvement of their assets.

To ensure quality, delivery time and costs of investment projects, we make use of robust systems, tools and processes, many of which created by Pöyry. All of these applied to the language of the minerals processing industry.

The following structure describes Pöyry´s offer for the mining and metals sector:

• Conception and Planning(selection and evaluation of the project, desing planning, evaluation of geological, geophysical and geochemical information, investment estimate, project time schedule, mineral rights, planning and management of mineral exploration).

• Exploration and Prospection(geological recognition and mapping, evaluation of geological environment, geochemical and geophysical drilling, sampling and analyses, well drilling and trenches, selection of priority targets for drilling, planning and supervision of drilling and sampling, chemical analyses, calculation of geological reserves(resources).

• Pre-Feasibility(technological characterization of ore, environmental characterization, preliminary definition of mining method, preliminary definition of process route, conceptual design of mining and beneficiation plant, investment and costs preliminary estimates, market studies, pre-feasibility studies, elaboration of EIA-RIMA, license of installation and operation).

• Mining(open-pit mining, underground mining, elaboration of mining plan, dimensioning and selection of mining equipment, calculation of mineable reserves according to the criteria of the JORC, infrastructure for mining, opening and development of mine and its accesses, solutions for mine drainage, tailing dams and waste pile, mine geology, planning and control of health, safety, hygiene and environment conditions, investment and costs estimates, feasibility studies, mine closure plan).

• Mineral processing(development studies of processes and definition of process routes, conceptual, basic and detailed project of physical and physical-chemical plant beneficiation, granular solid and pulp ores handling, projects of operational support facilities and support to operation, installation of plant infrastructure, investment and costs estimates, feasibility studies).

• Mineral transformation(hydro and pyrometallurgy of non-ferrous and precious metals, steel plants, ferroalloy, conformation and transformation of metals, fertilizers, cement and lime, glasses and ceramics, pigments, fillers and abrasives, raw materials for civil construction).

• Expedition(out-bound logistics [routes, ways(roads, railways, fluvial/maritime), ports and terminals], dimensioning of loading and unloading equipment).
