Side-by-side comparisons of hydrometallurgy equipment and process options: selection logic, cost ranges and decision criteria.
- Lime Neutralization vs Sulfide Precipitation: Which Wins
Sulfide precipitation vs lime neutralization compared across 10 decision axes: residual metals, sludge mass, USD per m3, and which effluent each route wins. - Hydrometallurgy vs Pyrometallurgy: How to Choose
Hydrometallurgy vs pyrometallurgy compared across energy, impurity tolerance, CAPEX and ore type, with route rules for copper, nickel and gold projects. - Forced Circulation vs Falling Film: 7 Selection Rules
Forced circulation vs falling film: 7 rules comparing heat transfer, scaling tolerance and turndown, so each hydromet liquor gets the right evaporator. - Solvent Extraction vs Ion Exchange: Which Wins at 2 g/L
Solvent extraction vs ion exchange: the 1–2 g/L, 200 m³/h crossover rule, compared on cost, selectivity and footprint, with decisive feed verdicts. - Pressure Filter vs Filter Press: Cake Moisture & Cost
Pressure filter vs filter press: membrane presses cut cake moisture to 8–12% w/w; continuous pressure filters win on cost per dry tonne above ~20… - Carbon in Pulp vs Carbon in Leach: Which Wins?
Carbon in pulp vs carbon in leach: CIL wins for preg-robbing and high-slime ores with 20–30% fewer tanks, while CIP suits clean, fast-leaching ore. - POX vs Biooxidation: Refractory Gold Route Compared
POX vs biooxidation compared: kinetics of hours versus days, 92–96% versus 85–93% gold recovery, and concentrate throughput cut-offs for refractory ore. - Continuous vs Batch Crystallizer: Selection Rules
Continuous vs batch crystallizer: default to continuous above 5 t/day; pick batch for campaigns and changeovers. CSD, CAPEX/OPEX, and quality trade-offs. - MVR vs Multiple Effect Evaporator: Energy, Cost & Selection
MVR vs multiple effect evaporator: steam economy, energy per tonne of water, CAPEX–OPEX breakeven and selection rules for hydrometallurgical plants. - D2EHPA vs Cyanex 272: Choosing the Right Extractant
D2EHPA vs Cyanex 272 compared: pH50 gaps, Ca co-extraction, Co/Ni selectivity and cost — with clear rules for picking the right extractant. - Thickener vs Filter Press: Choosing the Right Tailings Duty
Thickener vs filter press compared for mine tailings and hydromet slurries: duties, cake moisture, CAPEX and OPEX, water recovery, series flowsheets. - Tank Leaching vs Heap Leaching: 2026 Decision Guide
Tank leaching vs heap leaching compared on ore fit, recovery, residence time, CAPEX, OPEX, water balance, climate and ramp-up — with decision rules, cost… - ASME VIII Div 1 vs Div 2: Cost and Wall Thickness
