The slurry density is essential in various industrial applications, particularly in mining and construction. It helps estimate the handling requirements, flow rates, and other operational parameters.
Historical Background
Slurries, mixtures of solid particles and liquids, have been used for centuries, primarily for mining ores and transporting materials. The concept of slurry density emerged from the need to optimize transport costs, handling, and processing efficiency.
Formula
To calculate the slurry density, the following formula is used:
\[ SD = \frac{100}{\frac{C}{ds} + \frac{100  C}{dl}} \]
where:
 \(SD\) is the slurry density in kg/m³,
 \(C\) is the concentration of solids by weight (%),
 \(ds\) is the density of solids in kg/m³,
 \(dl\) is the density of liquid without solids in kg/m³.
Example Calculation
Problem:
Given:
 Concentration of solids (\(C\)) = 30%
 Density of solids (\(ds\)) = 2500 kg/m³
 Density of liquid without solids (\(dl\)) = 1000 kg/m³
Solution:
We calculate the slurry density (\(SD\)) as follows:
\[ SD = \frac{100}{\frac{30}{2500} + \frac{100  30}{1000}} \approx 1324.67532 \text{ kg/m³} \]
Importance and Usage Scenarios
Knowing the slurry density is crucial for:
 Designing pipelines and pumps to handle slurry mixtures
 Estimating material flows in mining and processing plants
 Optimizing costs associated with transport and material handling
