Formula and assumptions

S = T / (1 − b); B = S − T; W = S (1/C − 1); M = S + W.

C = total dry solids / wet paste mass; b = binder / total dry solids, both as fractions. Water is total required water: subtract water already in wet tailings separately. No strength, rheology or pumpability prediction.

T=100 t, C=75%, b=5%: binder 5.263 t, water 35.088 t, paste 140.351 t.
