Innovation and technology applied to mining needs

Chemical technology and field expertise to support mining operations

Every mining operation faces critical variables: production cycles, rock quality, water presence, heavy traffic, operational safety, and cost per ton. TREGA combines innovation, chemical technology, technical assessment, and on-site support to address those variables with practical, measurable solutions designed for sustained field performance.

Technical service areas

Four technical areas addressing critical mining-operation variables

Ground support, haul-road dust control, metallurgical recovery, process water, and rock and soil stabilization: each service area addresses a specific operating variable at the site. TREGA combines specialized chemical products, field assessment, and application engineering with technical criteria that can be transferred to the client’s operating team.

01

Ground support

Shotcrete

Operating challenge

Primary ground support in headings, drifts, and underground developments requires shotcrete with controlled early-age strength, low rebound, and consistent adhesion on rock with variable behavior. Cycle times, personnel safety, and development advance depend directly on its performance.

TREGA solution

Chemical admixtures for wet-mix and dry-mix shotcrete, mix design according to rock conditions, control of setting and early strength, and technical support for pumping, application, and field thickness verification.

Typical applications

  • Headings and development drifts
  • Stabilization of rock wedges and unstable areas
  • Ramps, shafts, and underground developments

02

Operational environmental control

Dust suppression

Operating challenge

Heavy equipment traffic on haul roads, pads, and yards generates dust that reduces visibility, increases occupational risk, accelerates tire wear, and drives up water consumption for road watering. Every operation has a different surface, climate, and traffic profile.

TREGA solution

Chemical dust suppressants selected according to surface type, climate, and traffic load, with dosage and application frequency calibrated to extend treatment longevity and reduce watering cycles without sacrificing dust-capture efficiency.

Typical applications

  • Primary and secondary haul roads
  • Leach pads, stockpiles, and yards
  • Loading, unloading, and maneuvering areas

Chemical process and water

Mineral processing and water treatment

Operating challenge

Metallurgical recovery, thickener operation, tailings handling, and process-water quality depend on slurry chemistry: pH, dispersion, flocculation, and recirculation conditions.

TREGA solution

Specialty reagents, flocculants, coagulants, and pH modifiers, with dosage adjusted to the ore and technical follow-up based on process indicators, water clarity, and operating consumption.

04

Stabilization and sealing

Rock and soil grouting

Operating challenge

Fractured rock masses, water inflow in underground workings, joint sealing, and soil consolidation require grouting materials and patterns selected according to permeability, flow rate, pressure, and expected operating loads.

TREGA solution

Grouts, microcements, resins, and chemical gels selected according to site conditions, with grouting-pattern design, controlled pressure, and verification of sealing or consolidation.

Frequently asked questions

Direct answers to evaluate a technical solution before requesting support

These answers explain how TREGA works, what technical information is required to evaluate each case, and how a practical solution is defined for actual mining operating conditions.

Talk to an expert

TREGA supplies chemical products and also provides assessment, technical selection, dosage support, assistance during application, and performance follow-up. The objective is for the solution to perform under the actual conditions of the mine, haul road, plant, or work site where it is applied.

Dosage is determined according to the product, technical data sheet, field conditions, and operating objective. Variables may include rock type, moisture, temperature, particle-size distribution, equipment traffic, water quality, reaction time, application method, and expected performance.

Dust suppressants can reduce watering frequency and extend treatment longevity. Application depends on road type, traffic, climate, moisture, particle-size distribution, and dust-emission levels. Each operation requires an application strategy aligned with the required performance.

A shotcrete evaluation requires information on whether the application is wet-mix or dry-mix, rock type, required strength, setting time, expected thickness, pumping conditions, moisture presence, fiber type, base mix, and the field ground-support objective.

Mineral processing plants and water-treatment systems may use flocculants, coagulants, filter aids, scale inhibitors, defoamers, rheology modifiers, grinding aids, mineral-separation products, and solutions to improve water clarity, settling, and recovery.

A grouting solution may be required where there is water inflow, fractured rock, permeable zones, material loss, open joints, voids, or a need for ground consolidation or stabilization. System selection depends on permeability, pressure, flow rate, material type, and geological conditions.

Yes. TREGA can provide technical data sheets, catalogs by solution area, and application information so the client can evaluate specifications, compatibility, preparation, dosage ranges, and technical feasibility before a trial or implementation.

TREGA focuses its technical presence in Mexican mining regions including Zacatecas, Sonora, Chihuahua, Durango, and Guerrero, with expanding coverage in San Luis Potosí, Sinaloa, Hidalgo, and Coahuila. Coverage is evaluated according to the project, urgency, service type, and operating conditions.
