Solution Mining
Solution mining offers several benefits compared to traditional mining methods including lower environmental impact, reduced energy consumption, higher resource recovery to deeper deposits, and reduced safety risk.
Depending on the mineral deposit, geological setting, project design, and operating conditions, solution mining may provide an alternative to conventional mining and extraction methods. Project-specific engineering and subsurface evaluation are necessary to determine whether these potential advantages apply to a particular deposit.
Overall, solution mining offers a range of advantages that make it an attractive option for extracting certain types of minerals, particularly those that are soluble in a suitable solvent and located in deep or challenging geological environments.
At IPT we specialize in providing innovative solutions to extract valuable minerals such as trona, lithium and uranium, dissolved in water/solvent, that can be extracted with solution mining techniques in a safe and environmentally sensitive process.

We can provide a wide range of services to evaluate, engineer and execute on your solution mining project.
We have completed both Front End Engineering Development (FEED) plans and execution plans for solution mining projects. Please contact IPT Solutions for your next project.
Solution Mining Project Evaluation
Evaluating the potential success of a solution mining project involves a thorough assessment of various geological, technical, economic, and environmental factors.
- Identify and characterize the target mineral deposit, including its size, depth, grade, and mineralogy.
- Provide hydrogeological and geological assessments to describe the conditions of the deposit, including the permeability and porosity of the rock formations, as well as the presence of any geological structures that may affect the feasibility of solution mining.
- Evaluate the solubility of the target mineral and determine whether it can be effectively extracted using solution mining techniques.
- Provide a resource estimation of the quantity and quality of the mineral within the deposit based on geological data, drilling results, and sampling.
- Determine the spatial distribution of the mineral within the deposit and assess its continuity and variability.
- Develop a hydrogeological model of the deposit to simulate the flow of fluids (e.g., water, solvent) through the rock formations.
- Evaluate the movement and dispersion of the solvent within the deposit, including any potential interactions with groundwater or other aquifers.
- Assess the potential for fluid containment and control during the solution mining process.
- Identify uncertainties that may require additional subsurface characterization before project development proceeds.
- Evaluate the suitability of solution mining techniques for extracting the target mineral based on the geological and hydrogeological characteristics of the deposit.
- Assess the feasibility of injecting the solvent into the deposit and recovering the mineral-rich solution to the surface.
- Identify any technical challenges or operational risks associated with the solution mining process and develop mitigation measures.
- Estimate the capital requirements for engineering and execution associated with establishing the solution mining subsurface operation, including equipment, services and labor costs.
- Evaluate the potential environmental impacts of the solution mining operation, including groundwater contamination, subsidence, and surface water discharges.
- Evaluate surface water discharges versus the installation of a brine water disposal well.
- Develop a comprehensive environmental management plan to minimize and mitigate potential impacts, comply with regulatory requirements, and ensure environmental sustainability.
- Identify and comply with applicable state and federal regulatory requirements for permitting, land use, water rights, and environmental protection.
Well Engineering for Solution Mining Projects
Well engineering connects geological and hydrogeological analysis with the physical infrastructure required for a solution mining project. Well placement, construction, completion design, and operating parameters should reflect the characteristics of the target formation and surrounding geology.
Engineering evaluations may address injection and recovery well configurations, wellbore integrity, anticipated pressures, fluid containment, and drilling requirements. The results of subsurface modeling can inform these decisions by providing a better understanding of expected fluid behavior within the mineral-bearing interval. Monitoring requirements may also be incorporated into well and project planning.
Because conditions vary among mining projects, well engineering should account for the specific mineral resource, formation characteristics, extraction objectives, applicable regulations, and site conditions.
Solution Mining Permitting
Regulatory planning should be incorporated early in solution mining project development. Depending on the project and jurisdiction, technical documentation may need to characterize the proposed injection interval, surrounding formations, groundwater resources, and potential pathways for fluid migration.
Permitting activities may also require engineering information addressing well construction, mechanical integrity, operating conditions, monitoring, and reporting. Developing this information alongside geological and hydrogeological evaluations can help establish a technically consistent basis for regulatory review. Specific requirements depend on the mineral, well configuration, jurisdiction, and applicable state and federal regulations.
From Feasibility and FEED Through Project Execution
IPT has completed FEED plans and execution plans for solution mining projects. FEED can bring together geological characterization, resource estimation, hydrogeological modeling, well engineering, permitting considerations, and subsurface economic analysis before a project advances toward execution.
As additional drilling, sampling, testing, or modeling data become available, technical assumptions can be reviewed and refined. This approach allows solutions mining planning to remain connected to the available subsurface data and project requirements throughout development. IPT Well Solutions can provide technical support across these project stages, from initial feasibility evaluation through engineering, regulatory planning, and execution planning.
