How do I calculate metal sulfate usage per tonne of NMC precursor?

The Metal Sulfate Usage calculator works back from your target Ni:Co:Mn ratio and precursor formula. It converts the metal content in each sulfate (nickel sulfate is about 22 percent Ni, cobalt sulfate about 21 percent Co) into kilograms of solution or crystal needed per tonne of hydroxide, then adjusts for co-precipitation efficiency and mother liquor losses so your purchasing volumes reflect real yield, not theoretical stoichiometry.

How much lithium excess should I add for calcination and what does it cost?

Most NMC recipes carry a Li/Me molar ratio of roughly 1.03 to 1.08 to offset lithium volatilization during firing. The Lithium Excess Cost calculator multiplies that surplus by your lithium carbonate or hydroxide price per tonne to show the added cost per kg of CAM. At current lithium prices, moving excess from 1.05 to 1.08 can add several dollars per kilogram, so it pays to trim excess without risking incomplete lithiation.

What is a realistic co-precipitation efficiency for pCAM hydroxide?

Well-controlled continuous stirred tank reactors reach 96 to 99 percent metal precipitation, with the balance lost to mother liquor and wash. The Co-Precipitation Efficiency calculator compares metal in versus metal recovered in the hydroxide cake so you can see how pH, ammonia concentration, and residence time affect yield. Pairing it with the Wash Water Load calculator shows the tradeoff between sulfate removal and dissolved metal carried out in wash.

How do I size calcination energy for a CAM firing line?

The Calcination Energy calculator estimates kWh per tonne from your peak firing temperature, dwell time, ramp rate, and kiln loading. Lithiation firing typically runs 750 to 950 C for high-nickel chemistries, and energy often lands in the range of a few hundred to over a thousand kWh per tonne depending on atmosphere. Combined with the Energy Intensity and Drying Capacity tools, it links furnace throughput to both cost per kg and your carbon reporting.

How does particle size distribution affect saleable yield?

CAM and precursor buyers specify D50, D10, D90, and span, and material outside window is downgraded or scrapped. The Particle Size Distribution Yield calculator estimates the fraction of a batch that meets the target D50 and span, then flows the rest into Scrap Recovery Value or Rework Cost. Tightening span from 1.2 to 0.9 usually improves packing density but lowers first-pass yield, so the calculator helps you find the economic sweet spot.

How sensitive is my cost per kg to nickel and cobalt price swings?

The Metal Price Sensitivity calculator flexes LME nickel and cobalt prices against your recipe's metal loading to show the swing in cost per kg. Because nickel dominates high-Ni chemistries, a 20 percent nickel move can shift cost per kg by several dollars. Running it alongside Supplier Risk and Quote Margin lets purchasing and sales agree on pass-through clauses and hedged pricing before signing offtake contracts.
