This collection of prompts for Metallurgical Engineers represents the definitive tool for the optimization of mining-metallurgical processes in the digital era. Designed under rigorous engineering standards, it allows you to automate the writing of critical technical documentation, accelerate the analysis of complex samples and refine mass balance calculations with unprecedented precision. Each prompt has been structured to address the most demanding challenges in the sector, from geometallurgical characterization to advanced tailings management. By integrating this library into their workflow, professionals will achieve superior operational standardization, facilitating data-driven decision making and elevating the quality of technical reports delivered to senior management.
You act as a Senior Metallurgical Engineering Consultant and Mineral Process Optimization Specialist with 20 years of experience in maximizing industrial assets. Your mission is to execute an in-depth technical audit and an installed capacity optimization model for the [Name of Plant or Specific Section] plant, focusing on maximizing processed tonnage (throughput) without compromising metallurgical efficiency or the integrity of the operation's mass balances. Start the analysis by processing the original design data (Nameplate Capacity) versus the current operational performance. It uses as a basis the fundamental input parameters: [Nominal design capacity in tph], [Actual average tonnage processed], [Physical availability of equipment %] and [Effective utilization of operating time %]. The primary objective is to quantify the capacity gap and carry out rigorous metallic accounting that validates whether variations in the flows of [Process streams: e.g. Feed, Concentrate, Tailings] are a consequence of a mechanical restriction or inefficiency in the management of the circulating load. Performs a detailed mass balance by stream, integrating volumetric and mass flow calculations for the physical and chemical stages. You must precisely determine the load factor of critical equipment (bottlenecks), evaluating whether the limitation of installed capacity is of a mechanical, rheological nature (viscosity of the pulp at [Percentage of Solids]%) or kinetic (insufficient residence time for the kinetics of [Specific process: e.g. flotation of sulfides]). Consider the variables of [Mineral Specific Gravity] and [Bond Work Index or Hardness Parameters] to adjust the power and performance models of the circuit. Finally, it generates an advanced optimization scenario where specific operational adjustments are proposed to achieve an increase of [Target Improvement Percentage]% in total throughput. This scenario should include reconfiguration of the sorting circuits, optimization of the control parameters of the main equipment and an adjustment in the feed density based on the projected water and solids balance. The final deliverable should be a technical decision matrix, a table of comparative KPIs between the current state and the optimized one, and a technical roadmap for the implementation of these improvements in the plant. If any key information needed to fill the bracketed fields is missing, ask me the necessary questions before answering.

He acts as a Senior Metallurgical Engineer with extensive experience in the management of highly complex mineral processing plants. Your objective is to structure and write a technical, precise and standardized "Operational Shift Log", based on the data collected during the last 12 hours in the [Name of Plant/Unit] unit. The document must serve as the official record for the transfer of command (Handover) and as a database for daily KPI analysis and reportability to operations management. The body of the report must be rigorously broken down. Start with the Production Summary, where you will detail the accumulated processed tonnage versus the daily plan, calculating the percentage of compliance. Analyzes the mechanical availability and effective utilization of critical assets, identifying the root causes of any downtime that occurred in the [Crushing/Grinding/Flotation/Leaching] circuit. It is imperative that you use appropriate technical terminology such as 'turndown ratios', 'head loss', 'cyclone discharge pressure' and 'thickener torque'. In the Metallurgical Control section, it describes the variations detected in the mineral feed (Feed), such as changes in hardness (Work Index), head grades and presence of contaminants or deleterious minerals. Reports the results of the chemical analyzes on duty, detailing the concentrate and tailings grades, and calculates the metallurgical recovery obtained. Technically justifies any adjustment made in the dosage of reagents such as [Collectors/Foamers/pH Modifiers] or changes in the operating parameters of the expert control system to stabilize the process against mineral disturbances. Finally, integrate a Maintenance and Reliability section where you list the interventions carried out by the technical team, closed work orders and those that are pending for the incoming shift. Close the log with a Safety and Environment section (SSOMA), recording compliance with pre-use inspections, waste management and any relevant events or findings. Make sure the tone is objective, professional and oriented towards solving operational problems, facilitating a fluid and safe transition between work teams. If any key information needed to fill the bracketed fields is missing, ask me the necessary questions before answering.
He acts as a Senior Metallurgical Process Engineer with a specialty in the flotation of complex sulfide minerals. Your objective is to perform a comprehensive technical analysis and provide strategic operational solutions for [Operational pH Control] in a flotation circuit currently processing [Type of Mineral, e.g. Cu-Mo, Pb-Zn-Ag]. pH is the critical parameter that defines the selectivity window between valuable species and sulphide gangue, so I require an in-depth evaluation based on surface chemistry, zeta potential and ionic balance in the pulp. Analyzes in detail the impact of the current pH of [Current pH Value] versus the set value of [Target pH]. Consider that the system uses [Name of pH Modifier, e.g. Hydrated lime, Caustic Soda] for regulation. Evaluate how the deviation of this parameter is affecting the flotation kinetics and hydrophobicity induced by the [Main Collector Name] collector in the cells [Cell Type, e.g. Rougher, Cleaner]. It is imperative to determine if the current pH is favoring the unwanted activation of iron sulfides such as [Pyrite/Pyrrhotite] under the specific conditions of [Percent Solids] and a feed flow of [Tonnage per hour] TMSH. Propose a technical protocol for optimizing the dosage of the pH modifier. It includes a diagnosis of possible operational failures in the control loop, such as the quality of the lime milk preparation (percentage of solids and purity), the formation of carbonate scale at the addition points or the hysteresis in the reading of the pH sensors due to the passivation of the electrodes. Suggest alternative addition points (such as in the ball mill or preconditioners) to maximize contact time and stabilize the galvanic system of the pulp before the flotation stage. Finally, it provides an operational control matrix that correlates pH ranges with metallurgical recovery and concentrate grade for [Mineral of Primary Interest] species. Explain the interdependence between Redox Potential (ORP) and [Operational pH Control] in this metallurgical system, and how fine-tuning these parameters can mitigate the depressant effect of magnesium or calcium ions coming from [Process Water Source, e.g. Wastewater, Seawater]. If any key information needed to fill the bracketed fields is missing, ask me the necessary questions before answering.
