a mixture of a finely ground (smaller than 1–0.5 mm) useful mineral and water. It is formed during such processes as the grinding of useful minerals before concentration, hydraulic mining, and hydraulic transport.
The density of pulp (the weight ratio between solid and liquid phases) and the number of particle-size fractions present determine the viscosity, which increases with an increase in density and in the number of particle-size fractions (in micron dimensions). The two factors also determine the sedimentation rate, which decreases with an increase in pulp density and with an increase in the fine particles present.
the principal mass of the spleen. A distinction is made between red pulp, which consists of reticular tissue whose loops contain mostly red blood cells, and white pulp, which consists of reticular tissue with lymphoid cells.
