<p>Methods and systems for blending fluids used in subterranean operations are disclosed. A first portion of a fluid component of the slurry is passed through a non-slurry pump in a first process line. A second portion of the fluid component of the slurry is passed to a mixing tub in a second process line. A solid component is added to the second portion of the fluid component of the slurry in the mixing tub. The second portion of the fluid component of the slurry is mixed with the solid component in the mixing tub so that the second portion of the fluid component of the slurry has a higher concentration than a desired downhole concentration. The output of the mixing tub is pumped through a slurry pump. The output of the slurry pump is diluted by adding the first portion of the fluid component of the slurry from the first process line and the diluted mixture is directed to a high pressure pump.</p>
