Weight vs Volume Chart
What is {primary_keyword}?
{primary_keyword} is the process of translating laboratory weight percent measurements into volumetric mineral abundance, ensuring geologists, metallurgists, and resource analysts can compare phase proportions accurately. Professionals use {primary_keyword} to reconcile assay results with petrographic observations and to plan processing routes. A common misconception is that weight percent equals volume percent; {primary_keyword} corrects that by accounting for density differences.
Exploration teams, mine planners, and financial analysts rely on {primary_keyword} when building block models or cash flow forecasts. Without {primary_keyword}, projected recoveries can be biased, leading to incorrect revenue projections. Another misconception is that small density differences do not matter; in reality, {primary_keyword} shows that even minor density shifts can swing volumetric proportions significantly.
{primary_keyword} Formula and Mathematical Explanation
{primary_keyword} starts with a known weight fraction and uses densities to convert mass to volume. The derivation ensures financial models stay consistent with metallurgical balances. By applying {primary_keyword}, you prevent dilution of grade assumptions and avoid overstated concentrate yields.
Derivation Steps
Step 1: Express the mineral weight fraction as Wm = weight% / 100. This anchors {primary_keyword} in mass terms. Step 2: Calculate mineral mass Mm = Wm × total mass. Step 3: Compute mineral volume Vm = Mm / mineral density. Step 4: Determine matrix mass Mt = total mass − Mm, then matrix volume Vt = Mt / matrix density. Step 5: {primary_keyword} volume percent = Vm / (Vm + Vt) × 100.
Each step in {primary_keyword} preserves mass balance and correctly scales volumes. This ensures metallurgical recoveries and financial valuations remain aligned.
Variables Table
| Variable | Meaning | Unit | Typical range |
|---|---|---|---|
| Total mass (M) | Sample mass for {primary_keyword} | g | 100–10,000 |
| Weight percent (Wt%) | Laboratory measured fraction for {primary_keyword} | % | 0–100 |
| Mineral density (ρm) | Density of target phase in {primary_keyword} | g/cm³ | 2.5–7.5 |
| Matrix density (ρt) | Density of host matrix for {primary_keyword} | g/cm³ | 2.2–3.2 |
| Mineral volume (Vm) | Volume derived during {primary_keyword} | cm³ | variable |
| Matrix volume (Vt) | Host volume during {primary_keyword} | cm³ | variable |
| Volume percent (Vol%) | Output of {primary_keyword} | % | 0–100 |
Practical Examples (Real-World Use Cases)
Example 1: Sulfide Ore
Inputs: total mass 2,000 g, weight percent 28%, mineral density 4.6 g/cm³, matrix density 2.65 g/cm³. Applying {primary_keyword}, mineral mass is 560 g, mineral volume about 121.7 cm³, matrix volume about 544.3 cm³, total volume 666 cm³, giving mineral abundance near 18.3 vol%. Financially, {primary_keyword} reveals the concentrate volume is smaller than weight suggests, affecting plant sizing.
Example 2: Industrial Minerals
Inputs: total mass 750 g, weight percent 62%, mineral density 2.72 g/cm³, matrix density 2.45 g/cm³. Using {primary_keyword}, mineral mass is 465 g, mineral volume about 171.0 cm³, matrix volume about 116.3 cm³, total volume 287.3 cm³, yielding 59.5 vol%. {primary_keyword} shows weight and volume align closely when densities are similar, guiding packing and logistics decisions.
These examples prove {primary_keyword} converts lab assays into process-ready volumetrics, protecting margin assumptions.
How to Use This {primary_keyword} Calculator
1) Enter sample mass, mineral weight percent, mineral density, and matrix density to initiate {primary_keyword}. 2) Review immediate results; the main banner shows mineral abundance vol%. 3) Check intermediate values to validate each {primary_keyword} step. 4) Copy results to share with teams and align financial models. 5) Use the chart to compare weight and volume outcomes from {primary_keyword} as densities shift.
Reading results: the higher the gap between weight% and vol%, the more density drives {primary_keyword}. Decision-making: if vol% is low, consider blending strategies; if vol% aligns with weight%, {primary_keyword} confirms density parity, reducing processing surprises.
Key Factors That Affect {primary_keyword} Results
1) Density contrast: Large differences increase the weight-to-volume gap in {primary_keyword}. 2) Moisture content: Wet samples can skew mass; dry weights stabilize {primary_keyword}. 3) Grain size: Heterogeneous grain size complicates sampling; representative splits improve {primary_keyword}. 4) Analytical precision: Assay error propagates into {primary_keyword}, impacting reserve models. 5) Blending strategy: Blends alter average density; rerun {primary_keyword} after each blend. 6) Economic cut-offs: Small shifts in vol% from {primary_keyword} can change marginal blocks and NPV. 7) Recovery assumptions: {primary_keyword} aligns concentrate volume with recovery curves. 8) Transport costs: Shipping is volumetric; {primary_keyword} ensures freight estimates stay accurate.
