CLAIMS
I claim:
1. A salt composition useful for facilitating the melting and removal of snow and ice comprising:
(a) salt,
(b) sodium silicate, and
(c) calcium magnesium acetate.
2. A salt composition as described in Claim 1 wherein (b) is sodium metasilicate.
3. A salt composition as described in Claim 1 further comprising triethanolamine.
4. A salt composition as described in Claim 1 further comprising sodium ferrocyanide.
5. A salt composition as described in Claim 1 further comprising at least one member selected from the group
consisting of diatomaceous earth, calcium silicate, fumed silica, powdered bentonite, talc and starch.
6. A salt composition useful for facilitating the melting and removal of snow and ice comprising:
(a) salt,
(b) sodium silicate, and
(c) calcium magnesium acetate;
wherein sodium silicate and calcium magnesium acetate are used in quantities effective for inhibiting corrosion.
7. A salt composition as described in Claim 6 wherein (b) comprises sodium silicate particles; and wherein said salt composition further comprises triethanolamine in an amount effective for thinly coating said sodium silicate particles.

8. A salt composition as described in Claim 6 further comprising sodium ferrocyanide in an amount effective for inhibiting caking of said salt composition.
9. λ salt composition as described in Claim 6 further comprising at least one member selected from the group
consisting of diatomaceous earth, calcium silicate, fumed silica, powdered bentonite, talc and starch; wherein said member is used in a quantity sufficient to prevent caking of said salt composition.
10. A salt composition useful for facilitating the melting and removal of snow and ice comprising:
(a) salt,
(b) from about 0.1 to about 10 parts by weight of sodium silicate per 100 parts by weight of salt, and
(c) from about 2.5 to about 30 parts by weight of calcium magnesium acetate per 100 parts of salt by weight.
11. A salt composition in accordance with Claim 10 wherein (c) is about 2.5 to about 20 parts by weight of calcium magnesium acetate.
12. A salt composition as described in Claim 11 wherein (b) is sodium metasilicate.
13. A salt composition as described in Claim 11 further comprising from about 0.01 to about 6.3 parts by weight of triethanolamine per 100 parts of salt by weight.
14. A salt composition as described in Claim 11 further comprising from about 0.05 to about 0.2 parts by weight of triethanolamine per- 100 parts of salt by weight.
15. A salt composition as described in Claim 11 further comprising from about 0.1 to about 20 parts by weight of at least one member selected from the group consisting of diatomaceous earth, calcium silicate, fumed silica, powdered bentonite, talc and starch, per 100 parts of salt by weight.
16. A salt composition as described in Claim 10 further comprising:
(d) from about 0.05 to about 0.2 parts by weight of sodium ferrocyanide per 100 parts of salt by weight,
(e) from about 0.01 to about 6.3 parts by weight of triethanolamine per 100 parts of salt by weight, and
(f) from about 0.1 to about 20 parts by weight of at least one member selected from the group consisting of diatomaceous earth, calcium silicate, fumed silica, powdered bentonite, talc and starch, per 100 parts of salt by weight.
17. A salt composition useful for facilitating the melting and removal of snow and ice comprising:
(a) salt,
(b) from about 0.1 to about 40 parts by weight of sodium metasilicate per 100 parts by weight of salt, and
(c) from about 30 to about 300 parts by weight of calcium magnesium acetate per 100 parts by weight of salt.
18. A salt composition in accordance with Claim 17 further comprising:
(d) from about 0.01 to about 24 parts by weight of triethanolamine per 100 parts by weight of salt.
19. A process for preparing a salt composition useful for facilitating the melting and removal or^snow and ice comprising:
(a) mixing together from about 0.1 to about 20 parts by weight diatomaceous earth, from about 0.1 to about 10 parts by weight sodium silicate, from about 0.05 to about 0.2 parts by weight sodium ferrocyanide and from about 0.01 to about 6.3 parts by weight triethanolamine to form a mixture;
(b) spreading said mixture over 100 parts by weight salt;
(c) mixing together said mixture and said salt in such a manner that particles of said salt become coated with said mixture; and
(d) and mixing from about 2.5 to about 30 parts by weight per 100 parts of salt by weight of calcium magnesium acetate into the salt mixture resulting from step (c).
